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.
Set the rotors Frozen during a hand
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.

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 RULE CARD / R51-0.3
Keep the object.
Declare the reading.
The 51 identities and their exact card–symbol dictionary are unchanged.
Deal five distinct identities. Tap HOLD below a card to keep it. Draw once to replace the others from the remaining 46. Hold all five, then choose Keep five to collect 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.
A settled hand in a strict ascending or descending five-rank order opens one free bonus spin from a fresh 51-identity inventory. It pays a guaranteed 5 jbits plus that spin’s gross poker award. The extra spin has no hold decision and cannot trigger another bonus. This is a declared play rule inspired by the order-sensitive 51 Twins exhibit, not a claim that the hand is a proved game loop.
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. It reports the base poker award; an order-run bonus can change which hold has the highest combined expected gross award.
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.
jbits are the site’s browser-local play currency with no cash value. Entries, saved hands, and awards use the same bank as the other games and Finance. The archive meter is local to this browser, not a global prize pool.

TWO DIALS / ONE IDENTITY
3 × 17 = 51
Mixed radix, not a new alphabet. Set u and v; i = 17u + v names canonical identity ai+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.
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.
