ReverseReversi app for iPhone and iPad

Alone on the train, two in a cafe, or with someone far away tonight.
A new minimalistic reversi where its best not to take the four corners.
It supports both battles using a single terminal and battles over online communication.

[rule]
Almost the same as Reversi.
[Special element]
1. The game is played in 4x4 squares.
2. On your turn, you can not only place stones in empty squares, but also select and turn over opponents stones. The stone that can be turned over is a square stone that sandwiches the opponents stone with the target stone and your own stone.
3. The number of turns is limited and the game ends after 20 turns.
[Win or lose condition]
1. When all the squares are filled, you win if you have a lot of stones.
2. If you have more stones after 20 turns, you win.
3. If there is a time limit, you will lose when the time runs out.
