Winners take the losing side's coins. A slice burns every round.
Instructions$PREDICT
1UP and DOWN each hold 100 coins.
If 50 of those UP coins were yours, 99 come back: your 50 plus half of the 98.
Every stock runs its own rounds on the same five-minute clock, and each one keeps its own pots.
Every bet lands in one of two pots. The side that calls it right takes the other pot.
