These are the 6 systems worth your time, out of 17 built. Each one has at least one decision that measurably changes whether you win — the rest reduce to "play your biggest card" and are not on this page.
Please play each fight to the end, win or lose, then answer the short survey that appears when you leave. Honest "I didn't get it" answers are the most useful thing you can give us — comprehension is the one thing we have not been able to measure.
The order below is shuffled for each person, so no system gets the advantage of always being first. Play them top to bottom. Your order stays the same if you come back.
One flame, one colour. Only cards matching the Wick's colour fire at end of turn, and the number die names the single slot you may play into.
What we are testing: Three real decisions — the colour you keep, where you place, when you reroll. The most evenly deep system in the lab.
Play a card now, or ETCH it onto a blank die face so it fires every time that face lands. Etched faces fire the instant the die stops.
What we are testing: Deepest single mechanic measured (65 pts). With etching disabled the win rate is 0%. Watch whether you work out that rolling is the damage.
Inscribe cards onto the four faces of the die, then roll it. The landed face fires what you wrote there.
What we are testing: Rigging made literal. Worth 45 pts — without inscribing, the win rate is 0%.
Today's result writes tomorrow's lucky number. The omen slot strikes at double.
What we are testing: The strongest targeting lever in the expansion wave (39 pts). Does the omen read as a plan, or as bookkeeping?
The dice belong to the Sentinel. It rolls them face-up a turn ahead and tells you which slot it will strike — and a struck card fires.
What we are testing: Planning against a declared threat (28 pts). The only system where the dice are the enemy's, not yours.
The Sentinel takes a stance each turn. Match it and strike double; be smothered and it gains block.
What we are testing: Reading a public tell (23 pts). Its reroll economy was just repaired — this is the first build where the stance can actually be answered.
