Summy
Similar to placing letters in Scrabble, teams take alternate turns placing 1-8 tiles to build a valid sum in horizontal or vertical direction. In each sum you must use at least 1 block which is already on table.
For each digit in a sum you get its value as victory points. So you try to use high numbers which are already placed. You can place high numbers from your own blocks too, but your opponents can profit when you place them easily available and combinable with other placed blocks. You should also try to hold good combinations of digits and operators for later turns.
While it requires calculating, it is more a puzzle game than a math game. You mainly search for possibilities by using deduction logic instead of calculating (which is induction logic).

Rules summary
Core Mechanisms
- Sums: Players place blocks with a digit ( 0 1 2 3 4 5 6 7 8 9 ) or a mathematical symbol ( + – x : = ) to form sums.
- Crosssum: A block can be part of 2 sums (1 horizontal and 1 vertical).
- Not like SCRABBLE: When sums are parallel adjacent, the connected blocks don't need to form a sum!
- Score: Each digit in a formed sum earns you points equal to the digit.
Turn Structure
1) Use blocks to make a sum. Or discard blocks (these go out of the game).
2) Score the digits in your sum as points.
3) Refill your hand to 8 blocks again.
Contents
- Blocks with a 0, 1, 2, 3, 4, 5, 6, 7, 8, or 9. (6 of each)
- Blocks with a +, –, x, or :. (5 of each)
- Blocks with an =. (14)
Preparation
- Place an '=' in the middle of the table.
- Mix the other 93 blocks and deal each player a hand of 8 blocks.
Placement Rules
- - On your turn you can make only one sum.
- - Each new sum contains at least 1 block from your hand and at least 1 block already at the table.
- - Each sum is read from left to right or top to bottom.
- - Sums can lay parallel adjacent. The parallel adjacent blocks don't have to form a sum.
- - The space before and after a sum must be and remain empty.
- - Each sum must contain exactly one equals sign ('=').
- - Before the '=' must be one (example: '1+2=3') or more (example: '1+2+3=6') operators.
- - After the '=' must be a number only.
- - Numbers in sums consist of 1 or more digits. (example: '8x15=120')
- - Multiplying (x) and dividing (:) get executed before adding (+) and subtracting (–).
End of the Game
The game ends when all players don't make a sum while the stock of blocks is empty.
Score
For each sum, you score all its digits as victory points. (example: The sum '8x15=120' brings 8+1+5+1+2+0, so 17, victory points)
