How do you play this game? There are no instructions. Do I mark all the balloons, or just some? x.x

If you've ever played Minesweeper, it's the exact same rules.

And you don't need to mark the stink bombs to win, that's just so you can keep track as you play and so you don't accidentally click a bomb you've already found.

It's been a really long time since I played mine sweeper. I don't even think they make it anymore. So the objective is, don't hit a bomb lol

Okay, so at first, you just click at random, and that'll clear that balloon. If there's no bombs around, it'll clear a bunch. Then you'll have some broken balloons with numbers on them, and the number equals how many bombs are touching that balloon. And it counts diagonals too, not just left, right, up, down. So you look at the numbers to logic out where the bombs are. And the objective is to pop all the balloons without hitting a bomb.

Got it. Thank you :)
