Blokus board game : an open-source Android implementation of the popular game.
Smooth Drag & Drop user interface.
Blokus is a family game involving four players and a board with 20 x 20 squares.
No ads at all.
Each player starts with 21 pieces.
"For first round, I must place a piece so that it touches one of the corners of the board"
"Next, a piece must be placed so that it touches a corner of one of my own pieces.
It may touch several corners, but never any side/edge of my pieces!" Look at screenshots or at the video.
The game has a nice and natural User Interface : just Drag & Drop the piece with the finger. Rotate a piece likewise.
You can flip a piece to its mirror position with a long-press gesture.

The end of the game is reached when every player passes.
