and finish. Build a streak by playing on consecutive days, and pick
your own symbol style for each daily.

- Remaining-count display on the number pad
- Highlight peers, matching numbers and mistakes — each toggleable

MAKE IT YOURS
Choose from numbers, letters, Greek characters, shapes or currency
symbols. Pick from seven accent colours, switch between light and dark
themes, and set the text size that suits you.

TRACK YOUR PROGRESS
Detailed statistics for every difficulty: games played, win rate, best
time, average time and best score. Earn trophies from Steel through
Bronze, Silver, Gold, Platinum and Diamond as you complete levels.

COMPETE
Sign in with Google Play Games to see how your total score compares on
the global leaderboard. Entirely optional — the full game works without

PLAY ANYWHERE
Every puzzle is generated on your device, so there's no internet needed
to play. Your game saves automatically, so you can put it down mid-

after a game over, double your score, or earn extra hints.
