Everythink

A new logic puzzle every day, the same for everyone, and all nine kinds to play as much as you like, at any difficulty. Every puzzle has exactly one answer you can reach with pure logic. No guessing, no ads, no account.

NINE KINDS OF PUZZLE
• Sudoku: 1 to 9 once in every row, column and box.
• Fence: draw one loop around the numbers.
• Bridges: join the islands with straight bridges.
• Islands: shade the sea around islands of the right size.
• Lanterns: light every cell without two lanterns seeing each other.
• Plots: split the field into rectangles.
• Weave: fill the rows and columns and find the picture.
• Cross Sums: digits that add up, with no repeats.
• Ladder: a Latin square with less-than and greater-than signs.

LEARN BY DOING
Every puzzle teaches itself before you play it: a quick hands-on lesson on a tiny example board, one step at a time. Replay any lesson from the puzzle's help button.

EVERY DAY, AND AS MUCH AS YOU LIKE
• One daily puzzle, the same for every player. The week ramps up: easy on Monday, expert on Sunday.

• Endless play: each new puzzle is made right on your device, so you never run out.
• Keep your streak by solving the daily puzzle.
• An optional daily reminder, only on days you haven't solved it yet.

MADE FOR THINKING
• Undo and redo, pencil notes, and crosses and dots to mark what you've ruled out.
• Broken rules show up in red, so you never chase a mistake for long.
• Pick up where you left off: every move is saved.
• Light and dark themes, on phones, tablets and foldables.

PRIVATE BY DESIGN
Everythink needs no account. It has no ads, no in-app purchases, no analytics and no tracking. Your progress stays on your device, unless you turn on the optional backup with Google Play Games, which keeps it in your own Google account.
