Sudoku: Fun Math Puzzle app analytics for October 31

Sudoku is the classic number puzzle, now with a calm mountain journey around it. Fill the 9x9 grid so every row, every column and every 3x3 box holds the digits 1 to 9 exactly once. Every puzzle has one solution and can be solved by logic alone, no guessing. HOW TO PLAY - Tap a cell, then tap a digit to place it. - Turn on Notes to pencil in the digits a cell could still take; they clear themselves as you fill the grid. - Undo and Erase are always free. - A wrong digit costs a heart. Lose all three and the level is over, but your grid is kept for the next try. 300 PUZZLES THAT GROW WITH YOU Start with quick, gentle boards and work up to bigger, trickier ones. Every new solving technique is taught on a calm lesson board with a short tip before any hard level asks for it: pointing pairs, hidden pairs, box-line reduction, naked pairs and triples, X-wing and more. HELP WHEN YOU NEED IT - Hint fills in the next cell you can work out. - Number Sweep places every remaining copy of one digit. - Complete Row fills the emptiest row in one go. A MOUNTAIN TO EXPLORE Travel through 15 alpine places, from Edelweiss Meadow and Waterfall Gorge to Summit Hut and Golden Larches, with gifts along the way. Collect 135 Alpine Keepsakes cards in 15 sets, win levels in a row in the Victory Run for growing rewards, and join seasonal events on your home screen. Relaxing piano music, clean big digits and a soft blurred view of the mountains keep every puzzle easy on the eyes. Take your time: there is no clock. Sudoku needs an internet connection to play.
