If there’s only 1 player, they play with all 70 tiles. With two players, each one has 35 tiles. Each player gets the same binary equation of 8 randomly arranged tiles, as shown below:
Put any 8 tiles you want, but avoid having zeroes (black tiles) for the last tiles of both rows simultaneously, as it limits the number of possible equations.
This game teaches you how to count in binary with the help of GEMJI tiles. First, you need to remember that there are only two numbers in the binary system: 1 and 0. A black GEMJI tile represents a 0, while a white tile - a 1. You don't need to consider any strokes on the GEMJI tiles; just look at the colors. With that in mind, here is how to do basic addition and subtraction:

To carry one, you can use a random vertical tile as a signifier to help you remember:
If you’ve carried one from the last column of the equation, you can simply leave it as a new column to the left:
The players decide how to solve the equation - by either adding the two rows or subtracting them. The direction in which it must be solved is right to left, column by column.
Each player starts solving their equation by placing the sum of each column directly below it, forming a new row. They continue solving every last two rows until they run out of tiles.
The winner is the first player to solve their equation correctly. Single players must calculate X number of rows for YY amount of time and this try to beat themselves each new game.
To increase the level of difficulty, you can calculate each previous row, instead of only the last two ones.
Single player tip: Make the game longer by reusing the topmost row of tiles to continue solving equations until you decide to stop.
