Blokus is a fun board game to play with both your friends online or with computer AI locally. Instruction: 1. Select a piece you want to place on the board; The larger the piece, the more points you earn! 2. For the first piece, you need to touch the starting point of your color on the board; For later pieces, you need to connect with previous piece ONLY with corners, no edge touch! 3. Try to place as many pieces (and points) on the board, while limit your component space so your component has no room to place pieces! The AI difficulty will increase as you play better! You have to win 2 consecutive games to proceed to the next level! Think hard to beat the AI! To play with your friends or anyone else online, you need to sign in GameCenter using your AppID, then choose to start online game. For online games, place your first piece to start the matching process, or join games started by others. Have fun!

Verdict

FourthPlayer's advantage is in-app purchases (none vs 1) and iOS requirement (10.3 vs 15.0). On ads and device support there is nothing between them.
