## What is Kazutsumi?

A number-place puzzle with big, easy-to-read numbers. Friendly for first-timers.
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.

■ "How to Play" for beginners
Six puzzles, starting on a small board. A pointing finger shows you where to tap, one step at a time.
Whether it's your first time or you just want a refresher, you'll be playing right away.

■ Today's Puzzle
One puzzle a day, the same for everyone. Choose 6×6 or 9×9.
Clear either one to earn a stamp on your calendar. Keep going and watch the stamps add up.
A new puzzle arrives at midnight Japan time.

■ Free Play
Pick a board size and Easy, Normal or Hard, and play as many puzzles as you like.
Unfinished puzzles are saved automatically.

■ Tsumikichi cheers you on
When you complete a row, when you're almost there, when you pause for a while.
Tsumikichi the owl offers praise and encouragement, and never rushes you.
