LinkedLab

The four games in LinkedLab will be familiar to anyone who plays LinkedIn's daily puzzles. Clusters splits the grid into rectangles that match the number and shape clues. Synapse joins numbered checkpoints in order with one path through every cell. Polarity balances suns and moons while following the clues between cells. Isolates places a queen in each coloured region, with one per row and column and no two queens touching.

Every day there are Easy, Medium and Hard boards in each game. Daily progress is saved on your device, streaks and achievements build as you play, and your personal best is your fastest combined Easy, Medium and Hard time in each game. With Game Center connected, each game has a daily ranking. Finishing all four games marks the day complete, lets you share it, and unlocks Queen Flight, a short tap-to-fly bonus game. Outside the daily set there is endless practice in any puzzle family, with Undo, Hint, Reset and illustrated rules, and the built-in puzzles work offline.

The app comes with 12 visual themes, from a plain Classic look to high contrast and monochrome, plus region patterns, Reduce Motion and VoiceOver support. An October 2026 update added a Halloween theme with spooky queens and Synapse ghosts.

LinkedLab is made by Gal Itach of Valorem Apps and came out on iPhone, iPad and Mac in March 2026; the developer says it is free and ad-free there. There is also an Android edition with its own versions of the four puzzles, called Crowns, Sun & Moon, One-Line Path and Patches, plus a physics stacking game; that edition shows ads.
