Overview
- —64 numbered cards (1–64)
- —2–6 players
- —Each player starts with 10 cards
- —4 shared rows on the table
Objective
Avoid collecting penalty points. The game ends when any player reaches 64 penalty points — the current round completes first. The player with the lowest total score wins. Tied lowest scores count as a shared win.
Turn Structure
- 1.All players simultaneously choose and reveal one card.
- 2.Cards are placed in ascending order into rows.
- 3.Each card goes to the row with the closest lower number.
- 4.The 6th card placed in any row triggers a penalty — that player collects all cards in that row.
Scoring
| Condition | Penalty Points |
|---|---|
| Most cards collected (any pile) | 1 pt per card |
| Multiples of 5 | 2 pts |
| Multiples of 10 | 3 pts |
| Multiples of 11 | 5 pts |
| Cards 13 and 55 | 8 pts (overrides all other rules) |
Action Cards
There are 3 of each action card type.
| Card | Numbers | Effect |
|---|---|---|
| Block |    | The chosen row is treated as non-existent for the round — no one can place in it or collect from it (including the player who played the Block card). Cards that would normally go there are redirected to the next valid row. |
| Shield |    | This card can be placed as the 6th card in a row without taking the row. If it is lower than the last card in every row, you may place it in any row without collecting any cards. |
| Decreasing |    | Reverses card placement to highest-to-lowest for the round. Multiple Decreasing cards do not stack. |
| Switch |    | Swaps the player's revealed card with any other player's card before placement. |
Action Card Rules

End of Game
- —When any player hits 64 penalty points, the current round completes fully.
- —The player with the lowest total score wins.
- —Tied lowest scores count as a shared win.
