Field notes
Free browser play. No accounts, deposits, bets or cash prizes. Points cannot be bought, withdrawn or exchanged for money.
Random does not mean “due”
Understand independent trials, streaks and changing card probabilities with examples from Win Zoo, Win Curve and Win Cards.
An average is not a promise: points, probability and RTP
Calculate an expected point score, distinguish an average from a guarantee, and understand why free game points are not a monetary RTP.
Memory, skill and chance: what can practice change?
Learn which decisions affect WIN games, how to practise timing and memory, and why a good result is not always evidence of skill.
Sources and supported claims
WIN rules, scoring and worked game examples are documented by the WinWinWin team from our own implementation. External sources support the general concepts below, not our game-specific numbers or claims of certified randomness.
The expected value of a sum is the sum of expected values, including dependent outcomes. This supports adding the five line expectations in the Zoo example.
Independent trials do not change the next probability; drawing cards without replacement changes the remaining probabilities.
Expected value is the sum of outcomes weighted by their probabilities. A long-run mean does not guarantee a short-session result.
RTP describes money returned relative to stakes over many plays, not a guaranteed return in one session. This source explains the term; it does not certify WIN games.
