Zolva

Zolva is Sudoku, reimagined — a calm, beautifully typeset number puzzle
you can pick up anywhere, with or without a connection.

A NEW PUZZLE EVERY DAY
Each day brings one fresh Daily Challenge. Complete it to build your
streak, and watch the month fill in on your calendar. Miss a day and the
puzzle is still there waiting — you can pick up exactly where you left off.

RACE YOUR FRIENDS
Challenge a friend to a live head-to-head race on the same puzzle and
watch it play out in real time. Add friends with a simple share code —
no account, no email, no password required.

LEADERBOARDS
Compare your Daily Challenge times against players worldwide, or just
against the friends you've added. Pick a display name and you're in.

FOUR DIFFICULTIES
Easy, Medium, Hard and Expert, each with its own saved game. Switch
between them freely — every difficulty keeps its own progress, so an
unfinished Expert puzzle is still waiting after a quick Easy round.

BUILT FOR FOCUS
• Clean, serif-set numbers that are easy to read
• Notes mode for pencil marks
• A running timer and a three-mistake limit to keep you sharp
• Hints when you're stuck — earn one by watching a short video, or use
the ones you have
• Light and dark themes, or match your device automatically
• Optional calming background music, sound effects and haptics

PLAYS ANYWHERE
The full game works offline. Puzzles, progress, statistics and best
times all live on your device — no connection needed, no account to
create. Only the leaderboards, friends and races use the internet, and
they're entirely optional.

TRACK YOUR PROGRESS
Best times per difficulty, games completed, and streaks — all in one
statistics screen.

Zolva is free and supported by ads. If you'd rather play without them,
a one-time "Remove Ads" purchase is available, and hint packs can be
bought if you want a few more. Neither is required to play or finish
any puzzle.
