A fresh challenge every time
Start with a daily workout or explore games for memory, attention, speed, flexibility, logic and math.
Daily Grove puzzle
One board. A new puzzle every morning.
Place one walnut in each row, column and coloured patch, with no two touching. Everyone gets the same daily board, from an easier Monday to a tougher Sunday. Undo moves, clear the board or use a hint when you need it.
Your progress
See how your own play changes
Follow your Walnut Score, skill chart, personal bests and activity calendar. Your score reflects the levels you reach and your accuracy, and compares you with your own past play. It is not an IQ score or a medical measurement.
Make room for a small daily habit
Calm mode
Play without the clock
Prefer time to think? Turn on Calm mode. Games end after a set number of turns, so you can focus on the puzzle without a countdown. Calm mode is included for free.
Daily rhythm
A streak that understands a busy day
Finish your daily workout to keep your streak going. One missed day each calendar week is forgiven. Optional reminders and Home Screen or Lock Screen widgets keep your next workout close.

Before you play
What is included for free?
Your daily workout, the daily Grove puzzle, five games you can play any time, your progress, streaks and Calm mode. Walnut has no ads.

Memory: Flash Grid, Echo and Pairs. Attention: Arrows, Number Hunt and Odd One Out. Speed: Snap, Catch and Reflex. Flexibility: Color Clash, Switch and Spin. Logic: Patterns, Tower and Grove. Math: Quick Math, Bigger and Dots. Pro unlocks all 18 at any time.
Can I turn off the timers?
Yes. Open Me and turn on Calm mode. Games end after a set number of turns instead of running against a clock.
What does the Walnut Score mean?
It combines the levels you reach and your accuracy, averaged across skill areas. It compares you only with yourself. Walnut is for entertainment and practice, and makes no claim to improve performance outside its games.
What happens if I miss a day?
One missed day per calendar week is forgiven. Finish a daily workout to keep building your streak.
Where is my progress stored?
On your iPhone and in your normal iPhone backup. Walnut has no account or analytics. Deleting the app deletes its local progress; you can also erase progress from the Me tab.
Make a little time for play.
