Bridge
Order by the length of the main span, shortest first. Place all 41 cards on one timeline, one at a time — three wrong guesses and the run is over.
Every card in this deck carries a hidden value on the same scale — heights in metres — and the run is one long sorting problem. The first card is dealt face up. Each card after it goes into the gap where you think it belongs, and the value only shows once it lands. Get it wrong three times and the run ends with whatever you had placed.
This deck can also be shuffled together with any other deck measured in heights in metres — tick several on the deck tree to build one longer timeline out of them.
28 of the 41 cards you could be dealt, plus 13 more. The values stay hidden until you place them.
