What players get
Playing with colors
A board of colors
Numbers 1 to 9 become 9 distinct colors. Same classic Sudoku rule: no repeats in any row, column or 3×3 box.
Classic and Purist
Classic with lives, mistake feedback and hints. Purist with no help at all, for experienced players.
Color notes
Tiny color dots in each cell to mark the options you are considering. A must on the harder levels.
For everyone
Designed for a broad audience, including kids and people with numerical dyslexia. A colorblind-friendly palette is ready.
Friends & duels
Real-time 1v1 duels
Both players get the same puzzle and bet 0, 10, 25, 50 or 100 coins. The winner takes double, and the result shows up as soon as your rival finishes.
Friends
6-character codes, username search, requests (send, accept, decline, block) and a friends leaderboard.
Progress & rewards
Levels and XP
Every game earns XP, with bonuses for no hints, no mistakes and the daily puzzle. Levels unlock as you go, with coins to spend.
Daily and weekly challenges
A daily puzzle that is the same for everyone, plus weekly challenges with growing goals and XP and coin rewards.
Streaks with shields
Daily streaks with growing bonuses, and a shield to protect them.
How it pays for itself
Ads in moderation
A banner on the home screen, at most one ad every 3 games (never two within a minute), and optional ads for hints or coins, with a daily cap.
Premium subscription
No ads, plus extra perks.
Its own look
A look that stands out
Layered gradients, translucent glass-like surfaces and soft floating circles.
Cyan and coral
A visual identity entirely different from Sudoku Play, born from the redesign Apple asked for before approving it.
Problems we solved
Apple rejected it as too similar
The problem: Apple rejected the app for being too close to Sudoku Play: swapping numbers for colors was not enough.
How we solved it: A full redesign with an identity of its own: glass-like surfaces, layered gradients and a cyan and coral palette.
→ Approved on the App Store, and that redesign became its signature look.
Playing offline without losing anything
The problem: Finished puzzles, purchases and duels had to stay safe even with no connection.
How we solved it: Everything is saved on the phone and sent when there is signal, while keeping an eye on the battery.
→ Zero data loss reported.
Crashes on some Samsung phones
The problem: Samsung's aggressive battery limits closed the app when it synced in the background.
How we solved it: On Android it now syncs when the app opens, when a game ends or when you change screens.
→ No more crashes, and players notice no difference.
Duel coins always add up
The problem: Winning, losing, drawing, declining, letting a duel expire or walking away all had to move exactly the right coins.
How we solved it: Each outcome is settled in one go, off the phone.
→ Balances are always right, in every case.
Two apps, one account
The problem: Two apps had to share players and friends without mixing up their games.
How we solved it: Account and friends in common; games, coins and stats kept separate per app.
→ A player can be friends in both apps with a single account.
What it proves if you want your own app
Through store review, even after a rejection
When Apple said no, the app was redesigned and approved. It is live on the App Store and Google Play.
One account for several apps
Players sign in with Google, Apple or as a guest, and use the same account and friends in Sudoku Play and Color Sudoku Play.
Works offline
Games, purchases and duels are kept on the phone and sync when the connection is back, without losing anything.
Real-time duels
The result appears as soon as your rival finishes, and coins settle on their own whether the duel is won, declined or expires.
Cheating under control
Every game is checked again off the phone: impossible times or suspicious moves do not count, and cheaters are quietly set aside.
Two languages and a guided start
Spanish and English, with a 6-screen interactive intro that teaches you how to play.
