Fill the grid so every row and column uses each number once and every < and > sign holds. Six sizes from 4×4 to 9×9, with a new puzzle each time. Futoshiki is a Japanese number puzzle and logic puzzle in one. Fill the grid so that each row and each column contains every number exactly once, and every inequality sign (＜ or ＞) between neighboring cells holds. The pointed side of a sign always faces the smaller number. Every puzzle is generated fresh for you and has exactly one solution. Every puzzle can be solved by logic alone. Start with small 4×4 grids and move up to 9×9 as the number puzzle gets harder. HOW TO PLAY • Tap a cell, then tap a number. • Turn on Notes to keep several candidates in a cell. • Numbers that break a row, column or sign are shown in red. SIX GRID SIZES • 4×4, 5×5, 6×6, 7×7, 8×8 and 9×9. • Solve a size three times to open the next one. HELP WHEN YOU NEED IT • A five-step interactive tutorial teaches rows, columns, signs and notes. Replay it any time from How to play. • Reveal: puts the correct number in one cell. Free on 4×4; on 5×5 and larger grids, after a short ad. • Check: marks the numbers you entered that are wrong, and after you confirm you can clear them all at once. The first check on each puzzle uses no coins; after that it uses coins. • Auto notes: for 100 coins, candidates are noted automatically for the rest of the puzzle. COME BACK EVERY DAY • Daily missions that reward coins. • Rankings by country. • Your puzzle in progress is saved, so you can pick up where you left off. If you enjoy logic puzzles and quiet mind games, give this number puzzle a try. Every grid is solved by reasoning alone, with no arithmetic needed.
