Logicell: Daily Logic Puzzles

Nine logic puzzles in one app, each solved by logic alone.

Every puzzle has exactly one solution and can be solved step by step without guessing. Each one is checked by a logic solver before it goes into the game.

Nine puzzles
• Stars: put one star in every row, column and color region. Stars never touch, not even diagonally. 500 stages and a daily puzzle.
• Nonogram: fill in cells to reveal a picture. The numbers give the length of each block of filled cells in that line. Over 500 picture stages, with two-finger zoom on large boards.
• Circles & Squares: fill every cell with a circle or a square. Each row and column has as many circles as squares, no three of the same shape in a row, and the = and × signs between cells must hold.
• Dot Count: place two dots in every row and column. Each number tells how many dots are in the eight cells around it.
• Number Walk: draw one line that starts at 1, passes through every cell once and visits the numbers in order. Thick walls cannot be crossed.
• Box Split: divide the grid into rectangles. Each rectangle holds exactly one number, and that number is its size.
• Lamps: place lamps so every open cell is lit. Light travels along rows and columns up to the walls, lamps may not shine on each other, and a number on a wall tells how many lamps touch it.
• Number Shade: shade cells so that no number repeats in any row or column. Shaded cells never touch, the remaining cells stay connected, and a shaded number must still appear unshaded in its row or column.
• Island Link: connect the islands with straight bridges, at most two between any pair. Each number is the island's bridge count, bridges never cross, and all islands end up connected.

Over 3,000 stages
Each puzzle has its own path of stages that grows bigger and harder step by step, so there is no difficulty menu to pick from. Challenge stages come up along the way. The first time you play a puzzle, a short example shows the rules.

A puzzle for every day
A daily star puzzle, sized by the day of the week: quick 6×6 on Monday, a full 10×10 on Sunday. Everyone gets the same puzzle on the same date. Clear any puzzle each day to keep your check-in streak going.

Hints that explain
Stuck? A hint first clears any cells that don't match the solution. Otherwise it plays the next logical step on the board, highlights the cells behind it and explains the technique in plain words.
You start with 3 hints and get 1 more each day you open the game. All nine puzzles share the same hints. When you run out, you can choose to watch an ad for another hint.

Learn as you go
When a stage needs a technique you haven't seen yet, a short tip with a picture explains it before you start. Every technique you have met stays on the Techniques screen of that puzzle.

Crowns for speed
Finish within the target time to earn 3 crowns. Your fastest time and crowns are saved for every stage, and the puzzle select screen shows your crowns and progress for each puzzle.
