Fillo - Crystal Version — About this game
Start with a nearby diamond and watch the space claimed as you move. A rival can undo part of that work, making the order of the route important. Use the push action where useful, leave room to turn and plan a compact circuit instead of retracing long stretches during each twenty-second challenge.
