THE PROSPECT WINDOW

Five rotors. Your decision.

A new reading of the same cards.

Deal five, hold any, then draw once or bank the hand.

One entry. One optional draw. No duplicate identities.

Tap a tile to read its other face.

Read the decision Exact conditional odds

Keep a hold pattern, then count every possible draw from the 46 identities not in the first hand. Discarded cards stay out. These are draw odds for this decision, not the opening-deal odds.

Deal a hand to compare a decision.

Reel motion

Reduced-motion preferences use an instant result. Reveal now ends the animation, not the draw.

Different valid wiring changes the mapping, not the uniform opening odds. The live moduli follow the remaining inventory: 51, 50, 49, 48, 47. A redraw starts at 46.

Slot	mod	a	b	digit	index	Identity

Each row records e = (a·digit + b) mod m, then removes that indexed identity. It is a reproducibility record of observed draws, not a fairness certificate.

THE POKER READING

The hand pays.

Hand	Gross points

Gross points, not profit. Low pairs and high-card hands pay zero. Aces are high, or low only in A–2–3–4–5. There is no 2♣ in this game.

THE ORDER READING

The record unlocks.

The published record's final five identities, in that order. Match them on the initial deal to add the local meter to the hand's award. Each paid deal adds 0.01 point; a hit resets the meter to 51.

Initial key chance: 1 in 281,887,200. The draw cannot create eligibility.

THE RULE CARD / P51-0.3.1

Keep the object.
Declare the reading.

The 51 identities and their exact card–symbol dictionary are unchanged. is an operable identity, not a picture that must be explained before use. Its paper symbol is another face of the same token; changing the display does not change a hand.

Deal five distinct identities. Press HOLD below any to keep them. Draw once to replace the others from the remaining 46, or bank the original hand. A redraw settles immediately. All five original identities stay out of the replacement inventory, including discards.

Poker reads an unordered hand. The archive lock reads an ordered string. A swap can preserve the poker award and change the jackpot result. That distinction is the experiment.

PROBABILITY HAS A DOMAIN

A rule, not a promise.

There are 2,349,060 possible five-card subsets of this 51-identity alphabet. Four are royal flushes. Those are opening-deal counts, before the player chooses a hold. The conditional-odds panel enumerates the appropriate remaining inventory instead.

The scrolling tiles are decorative travel, not a preview of future draws or a claim about which card nearly won. Only the five center stops form your hand. The numbered-ring styling is rotor-inspired, not an Enigma simulation and not encryption. Rotors are selection maps; no stored zeta ordinate is used as a random seed. The triangular offsets are a declared design choice, not a discovered probability law.

TWO DIALS / ONE IDENTITY

3 × 17 = 51

Mixed radix, not a new alphabet. Set u and v; i = 17u + v names canonical identity a_i+1. Neither dial alone identifies the token.

ONE DIAL / TEST THE GEAR

Not every step is a permutation.

For e = a·d mod 51, coprime steps reach all identities. A shared factor removes possibilities. The dots show reachable positions, not a play prediction.

Step a

m_j = 52 − j | e_j = (a_jd_j + b_j) mod m_j

Five live depletion rotors produce 51·50·49·48·47 equally likely ordered hands under independent uniform input digits. Five independent mod-51 reels instead allow duplicate identities; that would be a different game with a different score table. Changing to three- or seven-card play likewise requires new scoring and fresh probability counts.
