There is a game in which two people take turns to put some pieces with different shapes (similar to Tetris pieces), and whoever has more territory wins.

Blokus is an educational board game invented by Bernard Tavitian, a French scientist. With Bernard Tavitian's ingenious design and creativity, gladiator has won many awards all over the world.

Its rules of the game are simple, but interesting, allowing players to play their unlimited potential. At the beginning of the game, you should start from the starting point of the board and put your own colored pieces on the board in turn. Each piece can only be connected with the corners of the same color, and it is not allowed to be placed along the edge of the chessboard. There are often many players who tickle while playing, because during the game, you can't just bury your head in your cube, but you must also stop others from putting it. The excitement of competition makes the game more interesting.

A game, its rules can be explained clearly in half a minute, easy to learn, but difficult to master. Playing with four people is much more intense and fun than playing with two people.

I think it should be this. Similar to triangle, it is an educational board game.
