First, select one of the three tiles.
Then, place the tile somewhere on the 3x3 grid.
Repeat these steps 9 times.
For scoring, each set of adjacent matching tiles is worth the square of the number of tiles that makes up the set:
1 tile = 1 point
2 tiles = 4 points
3 tiles = 9 points
4 tiles = 16 points
Minimum score: 36
Maximum score: 100
My high score is 92. :) Post yours below!
