LUCK IT is the classic Star Battle puzzle — the same kind you know from LinkedIn's daily Queens. Stars become four-leaf clovers; the rules are identical.

How to play

The board is divided into irregular colored regions. Plant clovers so that all four of these are true:

One clover in every row

One clover in every column

One clover in every colored region

No two clovers may touch — not side by side, not even corner to corner

Right-click an empty square to mark it with an X, so you can keep track of the positions you have ruled out.

Every board has exactly one solution, and every solution can be reached by pure deduction. You will never have to guess.

Modes

Campaign — 500 levels

Boards grow from 5×5 to 9×9, and the reasoning grows with them: from a single square forced into place, to region confinement, to set exclusion. Clear a level for bronze, finish with half the clock left for silver, and 70% left for gold.

Endless

A constant supply of puzzles, every one of them new. Solve for as long as you like.

Relax — no clock

The same puzzles with the timer removed. Sit with a hard board for twenty minutes if you want to.

Daily Challenge

One board a day, and everyone in the world solves the same one.
