Every game in the Stake Engine catalogue is compared with every other studio's games. Identical event tables (same size, weights and RTP) and distinctive shared mode lineups are matched straight from the catalogue. Look-alike games are then deep-scanned in the background, which adds each mode's bet cost and max win, the game client's build files, and the structure of real round books from Stake Engine's public replay API. Matches that rest only on mode names or round-book structure are reviewed by an AI decision model, which drops overlaps that come from ordinary slot vocabulary or Stake Engine's public math SDK.

Both games use the same event table: the same number of books, the same total weight and the same optimizer-tuned RTP down to 12 digits. Studios that simulate their own games never produce the same table, so identical tables mean the math files came from the same place. Simple tables with a hand-set RTP (like uniform Plinko boards) can coincide, so those only count once a deep scan shows the books themselves match. “Same books” means the books match but were re-weighted to a different RTP.

Every Stake Engine game id records the moment the game was created, and we also know when each game first went live on Stake.com/Stake.us and when its art was uploaded. In each DNA family, the game that provably existed first is the original. Other studios' games in the family are listed as matches; the original studio's own later games are listed as same studio, since studios reuse their own math all the time. A game created after the game it matches went live could have been built from the live game; one created before it was live couldn't, so it's listed as a shared source — shared code, licensed math or one owner's two accounts. When five or more studios share the same tables, the family is shown as a shared math pack: its first game is only the earliest, not the source.

That two games share math, code or design — not how they came to share it. Studios license math from the same vendor, build on the same template, or publish under more than one account. Every match lists its evidence and both games' creation dates so you can judge for yourself.

All of them, automatically. The catalogue is re-checked every hour, so new releases are compared within an hour of being published, and look-alike games are deep-scanned in the background, newest first.
