Sudoku Duel

Sudoku, but you're not alone on the board. Sudoku Duel turns the classic number puzzle into a head-to-head battle. You and your opponent take turns placing digits on the same grid. Every correct digit scores points, so the big numbers are worth fighting over. When the board is full, the highest score wins. HOW A DUEL WORKS Take turns: one placement per turn Correct digits score their value, so a 9 beats a 1 Skill bonus: spotting a hidden single or a deeper deduction earns extra points Completion bonus: finish a row, column or 3x3 block to bank +10 Combo bonus: string together correct moves for up to +3 per move Guess wrong and you lose points, so think before you tap Watch what you leave behind: set up your rival with a juicy completion and they'll take it 100-LEVEL CAMPAIGN 10 worlds, from Rookie to Legend, each with 10 levels Hand-picked fixed boards that climb steadily in difficulty A boss at the end of every world Earn up to 3 stars per level: win, win with no mistakes, then win by a big margin Clear a level to unlock the next, and your stars, best scores and progress are saved on your device FOUR BOTS WITH DIFFERENT PERSONALITIES Solver: calm and methodical, plays the easiest logical move every time Greedy: always grabs the most points on offer Aggressive: steals your best moves and denies you big scores Expert: thinks several turns ahead Bots never guess.
