Everyone gets the same two, and each one has exactly one solution you can reach by reasoning alone. No guessing, ever.

If you enjoy Star Battle (also called Two Not Touch), Takuzu, Binairo or binary sudoku, you'll feel at home here.

CROWNS
A Star Battle-style puzzle. Place one crown in every row, every column and every colored region. Crowns can't touch, not even at the corners. Tap once to mark a cell with X, twice for a crown, and let auto-X clear the cells a crown rules out.

BINARY
A Takuzu-style puzzle, also known as Binairo. Fill the grid with circles and squares. No three of the same in a row, each row and column holds the same number of each, and no two rows or columns are identical.

SUMS, WITH LOGIC NOOK PLUS
A small Killer Sudoku without boxes. Each row and column holds every number once, and each dotted cage adds up to its clue. Sums has its own daily and Free play, unlocked by Logic Nook Plus: one purchase, no subscription, and every game added later is included. Crowns and Binary stay free forever.

HINTS THAT EXPLAIN
Stuck? A hint fills one cell that logic forces and tells you why, so you learn the move instead of copying it.

ONE DAILY, UNLIMITED PRACTICE
Each mode has one daily puzzle that counts for your streak. Missed a day? Replay any of the last 7 days' dailies. When you're done, Free play has unlimited puzzles in three sizes, from easy to hard, and they never touch your streak.

- A streak across both modes, with a week view
- Solve times, best times and a 7-day chart
- Share your time without spoiling the board
- An optional daily reminder at a time you pick
- Color-safe patterns for every region
