Butterfly Kyodai Rainbow

The board looks calm until every clear wing seems to lead to a dead end, and that's when Butterfly Kyodai Rainbow actually grabs you. You're tapping matching butterfly wings to free them, but the path between two tiles has to be clear first - other pieces block the way, and figuring out which pair to clear next takes real thought.

Clearing that last tangled cluster and watching the whole board empty out is the payoff, and with hundreds of levels there's always another puzzle waiting to test you the same way. If you get stuck, boosters bail you out so you're never stuck staring at one impossible knot.

It's built in the same connect-the-tiles spirit as Mahjong Connect, but wrapped in rainbow colors, daily rewards, special events and new wings to unlock as you go. Play it on desktop or mobile, straight in your browser, free, no download.

If you like the calm-but-tricky pull of Matching games, this one's worth clearing a level or two on right now.

Clear the entire board by matching pairs of identical butterfly wings as fast as you can.

Tap or click one wing, then tap or click its matching partner to connect and free them both. The path between the two tiles must be clear - other tiles in the way will block the connection, so plan around them.

If a level has you stuck with no clear matches left, use a booster to break through rather than staring at the board hoping something opens up.
