This game has some very interesting unique mechanic from which quite a challenging gameplay emerges, with the AI being decent enough (Hard & Aggressive settings) to be able to appreciate it.
I see a few here mentioning difficulty understanding it: You are the blue player (on the top), you can click on a cell you control, which rotates it 60 degrees clockwise, and that's your turn. You capture all cells connected.
If this was played among human players (wish it had local multiplayer option!), would suggest Obliteration as target (or like Go, both players passing, or a resign), as the mechanic sometimes implies strategies involving changing large areas back and forth.
Unfortunately the game seems quite fragile on my Firefox browser, crashing it often, seems to work all right in Chrome.
