The starting numbers are chunky 3D blocks, so you can tell them apart at a glance. The board is easy on the eyes.
Tsumikichi the owl cheers you on along the way.
■ Start small, at your own pace
Three board sizes: 6×6 with large cells that takes a few minutes, 9×9 for a longer think, and 4×4 that's done in a minute.
Small boards use only the numbers 1 to 6 and fill the whole screen.

Whether it's your first time or you just want a refresher, you'll be playing right away.
