🐏 The Lambing Pen of Perhaps

Slide a corpse to the exact midpoint between two towns, build every possible world in an unwatched lambing pen to find what the kohen is guaranteed, split the plump lamb from the lean one, and load the gift tray for Rabbi Meir and Rabbi Yosei

precision-tape slider + premise-grid deduction + possible-worlds enumeration pen + jurisdiction-courtyard parable toggle + gift-tray loader. A range slider moves a slain body between two towns while a wobbling tape refuses to read an exact tie (the Rabbis: impossible to be precise); a 2×2 grid of premises (precision possible/impossible × kerova excludes/includes several towns) where the player derives no heifer / two heifers / one shared heifer with a stipulation, then seats the first tanna, Rabbi Eliezer and Rav Amram’s Rabbis in their cells (18a:2–6); seven unwatched lambing nights from the new mishna (two first-timers bearing 2M, M+F, 2M+F, 2F+M, 2M+2F; one experienced + one first-timer bearing 2M, M+F) where the player taps newborns into each ewe’s birth order to build worlds, tracks the lowest kohen yield found, declares the guaranteed count, and an exhaustive enumerator reveals the worst world (‘perhaps both bore females first’); a plump/lean hand-out under Rabbi Tarfon (better one to the kohen) and Rabbi Akiva per Rabbi Yoḥanan (kohen takes the lean; meshammenin = the shumman is disputed), the one-died contradiction resolved by Rabbi Ami’s retraction, Rabbi Ḥiyya’s shepherd and homeowner folds, and an SVG courtyard whose corner shades to the kohen when Rabbi Tarfon grants him a share (Rava/Rav Pappa, 18b:10–12); closed by toggling the foreleg/jaw/maw tray for Rabbi Meir and Rabbi Yosei across the replacement-with-kohen case, Rabbi Elazar’s kohen-got-nothing case, and Rav Pappa’s uncertain-tithe case, each with its ‘lest you say’ pick

🐑 Whose Lamb Is It?

Count out Rabbi Tarfon's sela, shekel and ragya, pass lambs, donkeys and grain piles from hand to hand until someone is left holding them, then unlock why Rav Naḥman needed both of his inheritance rulings

coin-purse composer + pass-the-parcel custody relay + two-dial tzerichuta lock. Tap sela/shekel/dinar/ma'a coins into a purse to pay exact amounts: Rabbi Tarfon's generous sela, miserly shekel and middle ragya (Rava: three dinars, ragil here and there), the one-ma'a lean lamb that works for one who acts on his own (vs. the ragya for one who comes to ask), and the donkey's full value when there's no lamb (Reish Lakish via Ravina's not-stricter-than-hekdesh, with Rav Naḥman son of Rav Yosef's boiled-vegetables option); then ten custody chains where a token steps hand to hand across an animated track before the player rules who ends up holding it: a stranger redeeming another's donkey (owner, by the thief's double-payment proof), ten doubtful donkeys' lambs (tithed and kept), the kohen's gift lamb (exempt from tithe), donkeys and tevel inherited through a kohen maternal grandfather (kept), gentile-smoothed vs. Jew-smoothed piles bought from a gentile (exempt by 'your grain' vs. tithed-and-his), produce deposited with a Samaritan vs. a gentile (Demai 3:4 and Rabbi Elazar's framing), and the lamb that died before reaching the kohen (his from separation); closed by a lock that opens only when both dials name the real tzerichuta reasons (lambs stand separated vs. grain tithed from itself)

🫏 The Donkey Nobody Redeemed

Sort carcasses between village and market and watch 'its prohibition is its intent' collapse, scrub a firstborn donkey from birth to the cleaver under Rabbi Yehuda and two readings of Rabbi Shimon, then balance the scale that decides whether a woman is betrothed with it

village/market placement map + contradiction-finder + life-cycle timeline scrubber + legal-tool rack + balance-scale physics toy. Eight Okatzin 3:3 carcasses (non-kosher horse anywhere, kosher nevela anywhere, kosher bird and chelev in villages vs. markets, Rabbi Shimon's pig) drop onto a two-zone map and are ruled already-food vs. needs-intent, then the player multi-selects every ruling that refutes the issuro-chishuvo theory before the Gemara's reisha/seifa argument and Rava's conclusion, with a two-reading toggle on Nimos vs. Rabbi Eliezer's practice crow; a range-slider timeline of the firstborn donkey (alive: sale/rent value, alive: shearing/work, redeemed with a lamb, neck broken) where each stop is ruled permitted/forbidden under three lenses (Rabbi Yehuda; Rabbi Shimon per Rabba/Rav Nachman/Reish Lakish; Rabbi Shimon per Rabbi Yochanan), with the neck-break stop gated behind choosing the cleaver-from-behind over the reed/sickle/ax/saw/locked room; Rav Nachman's two proofs (the arifa gezera shava, Levi's lost-money baraita) each judged only-Rabbi-Shimon vs. Rabbi-Yehuda-could-be-the-tanna before Safra's and the Gemara's deflections; and an SVG balance scale for the Kiddushin 56b mishna where the player sets the donkey's value and toggles Rabbi Shimon / Rabbi Yehuda with an any-amount lamb / Rabbi Yehuda with Rabbi Yosei bar Yehuda's shekel minimum until nothing is left in her hand (Rav's donkey-worth-a-shekel case), closed by picking Leviticus 27:25 as Rava's source for the shekel over Numbers 18:16's rejected hekesh

🥛 The Et Hunter

Shimon HaAmasoni expounded every little 'et' in the Torah until he reached 'Et the Lord your God you shall fear.' Hunt the particles yourself, stack the Gemara's proofs that milk is kosher and watch three of them crack, then climb a ladder of strange-calf dilemmas the Gemara leaves half-open

particle-hunt word game + proof-tower judge + narrowest-reading ladder puzzle. Tap every אֶת (and the extra heh of ha-teme'im) across Exodus 20:12, Leviticus 11:4 and 11:31, earning coins for expounding (glosses: Ketubot 103a's stepparents and older brother, Rabbi Shimon's et ha-gamal = camel's milk, the heh = juice, gravy and sediment). Deuteronomy 6:13 unlocks last and forces the withdrawal choice, which sets the withdrawal counter equal to the expounding counter ('just as I received reward for expounding…') before Rabbi Akiva's Torah-scholars reveal. Then sort four camel derivations between Rabbi Shimon and the Rabbis. Next, judge six proofs that milk is kosher as hold or crack, naming the Gemara's objection for each one that cracks (benefit-vs-eating twice, sell-to-buy-food); the three that hold (David's ten cheeses with its 'commerce in wartime?' rebuttal, milk and honey, Isaiah 55:1) stack as bricks on a tower. Finally, pick exactly the rungs that two baraitot must cover in the cow→donkey / donkey→horse / cow→horse chain of dilemmas, where the Gemara narrows both to the first rung, then compare horns and hooves to reach the 'just a red donkey' answer, with an epilogue on Rabbi Shimon's head-and-most-of-the-body rule

🪙 Double or Nothing

A Roman officer named Kontrokos accuses Moses of cooking the books — a Levite headcount short 300 men, a treasury missing half its silver. Audit the census yourself, catch the Sanctuary's secret double-weight maneh, sort a litter of mismatched newborns, and unravel a rabbi's wordplay on Rephidim and Shittim

forensic-audit ledger puzzle + drag-free verdict sorter + name/derash toggle cards — two real Kontrokos-vs-Rabban-Yoḥanan-ben-Zakkai ledger discrepancies (22,300 individually-counted Levites vs. the Torah's stated 22,000; 201 talents 11 maneh collected vs. 100 talents spent on sockets) worked as multiple-choice audits with full reveals of Abaye's dayo principle and the doubled Sanctuary maneh, plus a live one-sixth-from-the-outside padding slider deriving Ezekiel 45:12's 60-shekel maneh; a six-case litter sorter for the new mishna (cow→donkey-shaped calf, donkey→horse-shaped foal, ewe→goat-shaped lamb with and without partial simanim, ordinary goat kid, camel→kosher-looking newborn) where firstborn status and eating status are guessed as two independently-scored verdicts per case before the daf's real reasoning reveals; and a four-card dialogue between Rabbi Chanina and Rabbi Eliezer toggling between Rabbi Eliezer's literal place-names (Rephidim, Shittim) and Rabbi Yehoshua's derash readings from the parallel baraita

🌾 Called the People?

A Levite snatches gifts meant for the kohen and Rav can't decide whether to make him pay: is a Levite counted among "the people" who owe the foreleg, jaw, and maw? Work the gift docket on nine real cases, then follow four failed proofs — one a genuine refutation — before Mareimar closes the file for good, and catch the daf ending mid-sentence on Ulla and the kohenet

three-bin repossession docket + multiple-choice doubt-proof gauntlet — nine real cases (untithed teruma, an undelivered foreleg/jaw/maw, gifts already in one kohen's hand, a poor owner keeping his own peret and olelot, withheld maaser ani, a cow's maw sold whole vs. by weight, unclaimed first-shorn wool, and an unsifted stew) sorted into מוֹצִיאִין / אֵין מוֹצִיאִין / פָּטוּר per the daf's actual sanctity, azivah-vs-netina, and intact-object tests, paired with a four-round gauntlet reconstructing Rav's real unresolved doubt over whether Levites are called 'the people' (the nine-kohen-properties baraita, the sanctity-principle baraita, the slaughter-for-whom baraita escalating into an explicit תיובתא, and Rav's own tannaitic-dispute rescue), closing on Mareimar's dual ruling and a click-to-reveal cliffhanger on Ulla, the kohenet, and the mincha law that the daf itself leaves mid-sentence

🐕 A Hair's Breadth

A dog that ate from a corpse lies dead across the threshold and four Tannaim rule on the house. Slide it, widen its neck, flip it around until the judges say what each challenge asks (or admit it cannot be done), fill Rabbi Shimon's two-of-three grid, scratch a thigh bone and a creeping thing's egg open by a hair's breadth, and go out and see the orifices, sinews, and seams that decide whether a touch reaches the flesh

constraint-satisfaction sandbox with live judges + scratch-off canvas + lens-reveal hidden-object — an SVG doorway scene where the player sets three real variables of Oholot 11:7 as the Gemara reads it (mouth in/out, neck under a handbreadth / a handbreadth counting walls / a handbreadth of hollow, past the doorstop line or on the outer threshold) while four judge tiles rule live (Rabbi Meir on the neck, Rava's Rabbi Yosei on hollow-plus-position, Rabbi Elazar on the exit route, Rabbi Yehuda ben Beteira always impure), and seven target-verdict challenges must be satisfied or declared impossible (Yosei-strict-and-Meir-lenient and ben-Beteira-pure are the traps); a 3×3 exactly-two-per-row-and-column logic grid for Rabbi Shimon's mould / barley-bone / golel-and-dofek across contact, carrying, and tent; a destination-out scratch canvas where a hair-thin stroke flips a sealed thigh bone or embryo egg from tahor to tamei, with Rav Oshaya's intent button and an embryo-tissue toggle; and nine cases (hide, kidney in fat, sealed and perforated bone, unbroken and tissueless eggs, half-earth mouse touched on either half, sea mouse) inspected with a draggable clip-path lens that reveals the orifices, sinews, and seams before ruling

🚪 Between Two Gates

A validly slaughtered animal is still twitching — out of the category of the living, not yet entered the category of the dead. Rule its ten real laws at the threshold (food impurity but not carcass impurity, the limb versus the flesh that parts from it, Abaye's double stringency, the trap of the invalid slaughter), probe the bird and the beast for the parts that are merely wood, and judge which gathering of alal carries carcass impurity

liminal threshold tug-of-war + anatomy pin-probe — a heartbeat nefesh-orb hangs in a doorway between an ember Living Gate and a bone Dead Gate while the player rules the ten real mefarkeset laws of Rav Oshaya's Tosefta and Abaye (takes food impurity, no carcass impurity, separated limb like ever min hachai, separated flesh pure, forbidden to bnei Noach even after death, doesn't shield swallowed items under a corpse's roof, bestiality still liable, Rabbi Yoḥanan over Ḥizkiyya, plus one-siman and stabbing trap cards that collapse the doorway), each correct verdict tugging the orb toward a gate before it drifts back to dead center for Rabbi Zeira's 'left the living, never entered the dead'; opened by numbered pins over bird-and-beast line art ruling beak tip / Rav Pappa's inner membrane, talon tip / base sunk in flesh, and horn shaft / blood-line base as 'joins' or 'merely wood', and closed by picking which of three alal collectors (adult, child, wind) creates carcass impurity per Rav Huna's da'at rule and whether the hide nullifies two clinging half-olives

⚗️ The Soul That Drinks

Work the alchemist's bench: congeal the blood, melt the forbidden fat, dissolve the chametz, liquefy a bird carcass over fire and over sun — stamp each verdict, then find the stringency that blocks each of the Gemara's attempted derivations, forge the one source-pair that carries consecrated produce, and swing the two exegetical lenses of Rabbi Eliezer and Rabbi Yehoshua

state-change alchemy bench + refutation forge — eight substances visibly change state in an animated flask (melt over fire, dissolve in water, congeal, rot in the sun) before the player stamps the daf's real verdict (Reish Lakish's three nefesh-includes-the-drinker readings, the sun-rotted carcass that stays pure, the lentil-bulk of sheretz gravy, liquids-don't-join-solids), then a derivation-blocking logic game where the player identifies the shared stringency that refutes each proposed source (karet, no period of fitness, never permitted, any-amount impurity, dayo) and forges the one valid source-pair for hekdesh liquids from bikkurim/teruma/chametz/carcass, capped by an Eliezer/Yehoshua don-minah lens toggle flipping the verdicts on date honey, apple wine, bikkurim beverages, and orla juice

hazard-navigation dinner simulator — an eleven-scene choose-your-action evening meal scored on three meters (guf/body, mamon/purse, ruach/spirit) where every choice is resolved by the daf's actual rulings (Rav Chisda's meat-then-cheese ban, Rabbi Zeira's wiping-bread tests, the first/middle/final waters baraita, Sodomite salt, the held-cup limits), with a signature flip-card after each of Abaye's eight traditions that turns his assumed mundane reason over to reveal Rabba's hidden one (evil spirit, poverty angel, witchcraft, demons), graded on Mar Ukva's vinegar-son-of-wine scale

Stage the angel's grip to see which thigh Yaakov lost, match five Sages to the five verses that keep a scholar indoors after dark, measure the ladder at eight thousand parasangs, and re-cut the angels' Kedushah until the Divine Name lands where the baraita allows it

top-down staging puzzle placing the angel in the three real positions the Sages reconstruct (face-to-face hug per Rabbi Yehoshua ben Levi and Rashi, at Yaakov's right hand per Rabbi Shmuel bar Nachmani's gentile and Rava bar Ulla's Torah scholar, or up from behind per the Rabbis) and reading off which thigh each blocking strikes, a five-verse/five-Sage single-use assignment of the sources for a Torah scholar not going out alone at night (Rabbi Yitzchak, Rabbi Abba bar Kahana, Rabbi Abbahu, the Rabbis, Rav), an evidence-dial derivation of the ladder's 8,000-parasang width from the plural of olim/yordim and Tarshish's 2,000, and a Kedushah composer where the player adds and removes kadoshes across three angelic companies until Rav Chananel's 1/1/1 becomes the Gemara's emended 1/2/3, validated live against the baraita's rule that angels may not utter the Name before three words, plus a seven-stop dial through the disputed frequency of the angels' song
