Lantern Merge

Turn a handful of dim lanterns into one bright festival light, standing exactly where it needs to be.

How it plays
Each puzzle shows its whole queue of lanterns from the start. Tap an empty cell, then Place. The new lantern merges with an equal-rank neighbour directly up, down, left or right, and grows one rank in the cell where you placed it. Merging continues while another equal neighbour glows, and when several match you choose which one to take. Light the marked pedestal with a lantern at or above the target rank before the queue runs out or the board fills. There is no timer and nothing is random.

Features
- 24 hand-made puzzles in four chapters of six, on 3x3 and 4x4 boards
- Five lantern ranks that differ in shape as well as colour
- Undo your latest turn, including all of its merges
- Hints show the intended solution step by step, and a guided mode walks you through it move by move
- Your fewest placements are recorded for each puzzle
- Progress and puzzles in progress are saved automatically
- Sound, vibration and reduced-motion settings, and screen reader descriptions for every cell

Optional ad
After you complete a puzzle, you can choose to watch one rewarded ad to use the Festival Night background for your next three completed puzzles. The ad never plays automatically and starts only when you tap the offer. It is offered only in India, only to players who say they are 18 or older, and at most two times per session and three times per day.

Purchase
Festival Lights is an optional one-time purchase that unlocks three extra backgrounds (Festival Night, Lotus Pond and Monsoon Dusk) and removes the ad offer. Puzzles, hints and undo stay exactly the same.
