Turn the tiles. Let the water through. Riomaker is a game about building rivers. Every tile has to fill with water, so twist them around until the whole thing flows from the source all the way to the goal. Keep half an eye on the clock. Each stretch gives you a set amount of time, and the water will not wait for you to make up your mind. No menus. No story to keep up with. The world is the map. Clear a stretch, plant your flag at the checkpoint, and the river carries you straight into the next one. The further you go, the more the landscape around you changes. Out of time? Spend a heart and pick up from your last checkpoint. Hearts are won in the whirlpools, and when they run out, you start over from the source. Wrong turn? So did the Mississippi.
