How to play
Lumisla is a logic puzzle from the Star Battle family. A board has 5×5 to 10×10 cells and as many colored islands as rows. You place the same number of lighthouses, following three rules.
Rules
One per row and column
Every row and every column has exactly one lighthouse.
One per island
Every colored island has exactly one lighthouse.
They never touch
Lighthouses can’t stand side by side, not even at the corners.
In the game
Controls
A cross rules a cell out; tap it again to remove it. A lighthouse needs two quick taps, so you never place one by accident.
Three lives
A lighthouse in the wrong place puts out one lamp and leaves a red cross. After three mistakes you start the level over, or once light a lamp after a short ad.
Lantern
Stuck? Tap the lantern under the board. It lights up a cell and says why, and you place the lighthouse yourself. A dark lantern lights up after a short ad.
Star
Tap the star, then an island: its lighthouse lights up by itself, and the cells it rules out get crosses for good. One star a day is free; you get another after a short ad.
Points and ranking
A finished level gives 10 points for each row of the board and 10 for each lamp still lit. Finish it without the lantern, the star or relighting a lamp, and you get 20 more. Once you sign in to Google Play Games, your points go to two rankings: this week and all time.
An ad never starts by itself: the game always asks first.
