A number puzzle you solve the way you would with a pencil on graph paper.
The number outside a line is the sum of the numbers that must stay in it. Erase what you do not need, circle what has to stay. When every row, column and colored block adds up, the board is done.
▪ No guessing
Every board has exactly one answer, and a solver checks that logic alone can find it before the board ever reaches you. Stuck? A hint points at the line to look at.
▪ Journey
Open one stage at a time, from canola fields through cherry blossom lanes and summer shores to a lotus pond. Each stage has three stars and a small mission — no mistakes, no hints, or beat the clock.
▪ Daily puzzle
A fresh board every day. Keep a streak going, and replay any past day from the calendar.
▪ At your own pace
No-hearts mode never costs you a life. Pick any size from 5×5 to 9×9, and send a board you liked to a friend with a challenge code.
▪ Small comforts
· Auto-erase clears the rest of a line once every keeper is circled
· Sound and vibration can be turned off in settings
· No account, no sign-in — your progress stays on your device
· Works offline
Pick it up like a pencil in a quiet moment.
Erase numbers until every line adds up. Like pencil on graph paper.
