Blokus by LaForce 1.2 ios官方版

The iPad implementation for the famous board game Blokus. Supports 2 players and 4 players. Originally programmed in 2017.

Rules:
Touch a block to select it, then drag to place it on board.
Each block should share a corner (but cannot share an edge) with an existing block of the same color, except for the first block, which should cover the dot of the same color. A block may not overlap with any other blocks.
When you cannot place any more blocks, tap "PASS".
Google "Blokus" for a more detailed introduction.

Menu: You can double-tap the checkerboard to return to the menu.
Online Mode: You can now play Blokus online via GameCenter. The first time you launch the app it will ask you to log in. You can only play local games if you do not log in.
Added a "SURE?" confirming phase to avoid touching "PASS" by mistake.
