MemoTrimo is a Memory game, or better say it is both Memory and Trimory in
one.

When you start a game, you will see a 36 squares big square (6×6), which is
filled with up to 18 different symbols, all hidden. You have to find those
that are the same by opening two or three (depending on the game mode)
squares. If you revealed the matches, they stay open; if not, they close
again.

You can play the game as Memory (18 different symbols and two open squares at
a time) or as Trimory (12 different symbols and three open squares).

For highscore purpose, the game counts the number of two or three square
groups you have opened.
