• 1–6 players. If 1 human, L and R join as computers. If 2 humans, L
joins.
• Start each round with a shuffled 54‑card deck (two jokers),
everyone gets 2 cards face down, total is a random 20–100, flow is
clockwise, and a random starter is chosen.
• On your turn: Everyone else looks away; your two cards are
revealed. Play a card, draw a replacement unless the deck is empty,
choose from allowed options to change the total, and state the new
total.
-
Non‑Ace/Joker: you may add the card’s number (no
points).
-
If the total is a perfect n‑th power, you may
take the n‑th root (earn
n points).
-
If the total is divisible by the card and the card is ≥4, you may
divide (earn 1 point).
-
Ace: add 1 plus the next deck card’s number, then
reverse play. No points.
-
Joker: set any total between 20 and 100. No
points.
Total must change. Taking roots when the total is 1 is not allowed.
When the deck is empty, keep playing without drawing until all cards
are played. That ends the round. The next round starts with the next
player clockwise from the previous round's starter. The game ends
after the selected number of rounds (default: 3 rounds).
