Lumen Tide

About the game

Drag two matching items together and they become one better item.

Lumen Tide is a calm merge puzzle set on a floating reef. The old tide-powered observatory has gone dark, and its great lens is broken. You have a salvage board, a stubborn streak and a grumpy crab for a foreman. Rebuild the place one merge at a time and wake the Lumen, the glowing tide that keeps the reef alive.

Merge and deliver

Tap the generators to drop driftwood, coral, glass and tools onto a 7x9 board. Merge pairs up through 10 tiers per family, from scraps to rafters, coral sprigs to reef arches, glass beads to prisms. Each restoration task asks for specific items: when they are all on the board, tap DELIVER.

The tide changes the board

The tide cycles through Low, Rising, High, Ebbing and Turn. Low tide drops small finds, High tide brings lucky ones, and at the Turn every generator drops one tier higher. Bank your pairs and time your merges.

Restore the observatory

36 tasks across 3 acts: patch the landing, light the galley stove, span the gaps between drifting platforms and finally seat the great lens. Watch each place come back in the restoration view, before and after.

A small story

Meet Marrow the mud-crab, Pell the sky-eel cartographer and the Tidekeeper, a quiet light inside the lens with a story of its own. Short dialogue cards, no cutscenes.

More to do

Clear junk and barnacle rocks, repair generators after storms, catch a Lumen Surge, and pick up side tasks and three daily quests.

Good to know

• Generator taps use energy (merging is free), which refills over time (1 every 20 seconds, up to 100).
• The game shows ads: a banner, an occasional full-screen ad between tasks, and optional video ads you can watch for energy and other rewards. Ads are non-personalized.
• Your progress is saved on your phone. The game itself works offline; ads need a connection.
• Colorblind tier glyphs, sound, music and haptics can be switched in Settings.
