Sharkdoku: Sudoku-Style Logic

Sharkdoku is a numberless twist for fans of ad-free Sudoku and relaxing logic puzzles. Enjoy ad-free play with no banners and no automatic ads between levels. Optional rewarded videos are available only when you choose extra help. SHARKS INSTEAD OF NUMBERS Find a home for every shark using three simple rules: • One shark in each color region. • One shark in every row and column. • Sharks cannot touch, even diagonally. Use Sudoku-style deduction to rule out squares and find the next safe move. Tap to mark a square. Double-tap the same square to place a shark. No number calculations needed. AN ENDLESS OCEAN OF PUZZLES A guided first level gets you started. Then explore endless, uniquely solvable puzzles with varied layouts and boards growing to ten sharks. Every level is free to play, with no subscription or paid puzzle packs. OFFLINE, AT YOUR PACE Play offline with no puzzle timer. Your board, notes, level, pearls and supplies are saved on your device, ready when you return. There is no energy timer or wait for lives to refill. Run out of squid lives? Restart immediately for free, as often as you like. A LITTLE HELP, YOUR CHOICE Start with five Hints and five Reveals. A Hint explains the next safe move; a Reveal places a shark. When supplies run out, you can choose a rewarded video for another hint, reveal or three squid lives. Videos require an internet connection and availability. You can keep solving and restarting without watching them. A DAILY REASON TO DIVE BACK IN Complete a new level each day to collect a fin. A seven-day streak unlocks a mystery chest of free hints or reveals. Optional local reminders can help you keep your streak going. A TIP, NEVER AN UNLOCK Enjoying your time in the ocean? The optional Tip jar lets you support the developer. Tips grant no hints, reveals, lives, levels or other gameplay benefits. Puzzle play stays free whether you tip or not. Find the sharks. Enjoy the splash. Keep playing your way.
