LinkedLab

Clusters asks you to draw rectangles that satisfy number and shape clues. Synapse switches to a continuous path through every cell, visiting numbered checkpoints in order. Polarity balances suns and moons. Isolates puts a queen in each colored region, with row, column and no-touching constraints.

That variety is the reason to consider LinkedLab. You can switch from planning a route to fitting shapes without finding a separate puzzle app for each ruleset.

The iPhone, iPad and Mac editions offer Easy, Medium and Hard daily challenges, plus built-in practice puzzles that work offline. The listing describes local daily progress, streaks and personal bests. Core puzzle play needs no developer account, while Game Center rankings require sign-in and internet access.

Eleven visual themes include Classic, High contrast and Monochrome. The advertised controls include region patterns, calmer effects, larger device text and VoiceOver support. Accessibility behavior was not tested for this note.

The checked Apple listing is free. Android has a separate game collection; compare its listing before choosing a version.
