Solitaire Lab
Does a rule change make solitaire easier? Don’t guess — test it on real deals.
📊 Run an experiment →How the lab works
- 🔮 Predict first. Pick which rule you think wins more deals — before you look.
- 👯 A fair test. Every deal is played BOTH ways, so the only difference is the rule.
- 🔍 A solver that never lies. Each deal is proven won, proven lost, or marked not sure yet when the search runs out of time.
- 📏 How sure are we? You get an “at least … at most …” range and a 95% interval — more deals make it narrower.
Meet the cast — the characters who teach this
-
Dealia (Mentor, a card-dealing raccoon) - asks what you predicted BEFORE you look at the data -
Twinnie Deals every hand twice - the same deals for both rules, so the test is fair -
Hedgeworth Never says more than the data can - reports at least ... and at most ... -
Maybelle Knows an unknown is a maybe, not a no - the search ran out of time -
Bigsby Knows more deals make the answer sharper - the interval gets narrower -
Lopsy Counts the deals where only ONE rule won - those odd pairs are the whole story -
Lanternby Knows the measuring tool is part of the result - a bigger search proves more wins of the SAME deals -
Glassby Knows FreeCell hides nothing, so a 'lost' there is a proof about the deal itself -
Tiebelle Calls it a tie when the two ranges overlap - no winner the data cannot back -
Seedwick Knows the same run seed rebuilds the same deals, so anyone can re-check your test -
Tabitha Keeps one row per deal in the CSV so you can draw the chart yourself -
Addison Knows a rule that only ADDS moves can never truly win less - reason before you run
