A calm logic puzzle, from a 6×6 mini to Summit Push. Every puzzle has one answer that logic alone can reach.
Trail Walk: Straightforward: look for the one number that fits.
Mountain Hike: Spot pairs and patterns.
Summit Push: Advanced tricks. Take your time.
Fill every empty square so each row, each column, and each box holds every number once. Mini puzzles use 1 to 6; Classic uses 1 to 9. Tap a square, then a number. Turn on Notes to pencil in possibilities. Check and Hint are there whenever you want a nudge.
Sudoku is a quiet logic puzzle: fill the grid so every row, every column, and every box holds each number once. There's no math, just careful looking. Our puzzles come in three levels named for the trail. Trail Walk puzzles need only simple scanning. Mountain Hike asks you to notice pairs and patterns. Summit Push takes patience and a few advanced tricks. Every puzzle has exactly one answer, and you can reach it by logic alone, with no guessing. New to sudoku? Start with the 6×6 mini, which uses the numbers 1 to 6 in boxes of two rows by three columns; it's part of Today's Trail Mix every day. Pencil in possibilities with Notes, undo any move, and use Check or Hint when you want a nudge. Hints explain why a number fits, so you learn as you go. There's no timer unless you turn one on. Play with a finger, a mouse, or the keyboard, or print any puzzle with its answer key on a separate page. Your progress saves on this device.
