Lumen brings together Hive, a hex block puzzle with prism lines and combos, and four level puzzles: Cascade, Bloom, Threads and Mosaic. Every level is generated to be fair, with no lives, no timers and no ads.
Drag glowing pieces onto a hexagon board and fill lines in any of three directions. Clear a line of one colour for a Prism, and chain clears for combos.
Hex match-3. Swipe a gem into a neighbour to line up three or more. Lines of four leave a star that bursts everything around it.
Tapping a hex flips it and its six neighbours. Light the whole hive, and match par for three stars.
Drag from each dot to its twin. Threads cannot cross, and every square has to be filled.
Picture logic. The numbers give the runs of filled squares in each row and column; paint the picture they describe.
Twenty levels of every puzzle and three hints a day are free. One purchase unlocks endless levels, unlimited hints, every theme and Hive Zen mode. No subscription.
Runs on: iPhone with iOS 15 or later, and Android phones with Android 7.0 or later.
