Betkyo odds data
Machine-readable tables behind the Betkyo Journal, exported from the casino game engine source rather than typed by hand. Each JSON file carries its provenance (source names the engine module, article the derivation, generated the export date) and a data object; the CSV next to it is the same table flattened. index.json lists them all.
| File | What it is | Derivation |
|---|---|---|
keno-paytables |
All forty keno payout tables (level × picks × hits), total-return multipliers | What a keno risk level actually changes |
plinko-multipliers |
Plinko bucket multipliers for every risk level and row count | Plinko, priced |
roulette-bets |
Bet kinds, pockets covered, multiplier, expected return; wheel order and red pockets | A roulette bet is a string |
blackjack-dealer-outcomes |
Dealer final-total distribution by upcard, infinite shoe, dealer stands on all 17s | Dealer bust odds by upcard |
koban-ladder |
Koban Flip cumulative multiplier after n straight calls, floored to cents | Designing Koban Flip |
fukubukuro-bags |
Item weights (millionths) and payout multiples for both lucky bags | Designing Fukubukuro |
