How to play Fill the giant 16×16 grid so that every row, column and 4×4 box contains the sixteen hexadecimal symbols — the digits 0 to 9 and the letters A to F — with no repeats. Tap a cell to select it, then tap a symbol to place it. The row and column highlight to help you spot conflicts at a glance. Pinch to zoom in on the big board, and double-tap to jump between the full grid and a close-up. Stuck on a cell? Tap Hint to reveal the correct symbol. Completely free — no ads, no accounts, nothing locked behind a purchase. There's an optional tip jar if you'd like to support development. Killer Sudoku cages Dashed outlines group cells into cages, each with a target sum shown in its corner. The symbols inside a cage never repeat and must add up exactly — extra logic on top of the usual row, column and box rules. Prefer to add up in hex? Switch cage totals between decimal and hexadecimal any time in Settings. Choose your difficulty Five levels from Very Easy through to Extreme — from a gentle introduction to a serious challenge. Track your score Every correct symbol earns points — and solving quickly, keeping a streak going and finishing under the par time all add bonuses on top. Harder puzzles score the most. A wrong guess breaks your streak, so think before you tap. Clean, distraction-free design Choose from a selection of light and dark color themes — no internet required. Prefer a relaxed solve? Zen Mode hides the score and timer and drops all penalties. If classic Sudoku has stopped stretching you, Hexways is the next level — a fresh giant puzzle every time.
