MONKEY AND BALLS

There is a small trend in shooting balls, a direction where developers change the faceless gun with some character, forcing him to shoot balls. This hero either throws the balls himself, or loads and directs the cannon that does it. We already have such gunners in our collection: pirate, chicken, mushroom... And now a monkey had joined their ranks. She listens carefully to you and throws the ball wherever you point.

But monkeys, as we know, rarely act selflessly. In this case, your gunner gets his own food. Among the bubbles that the monkey knocks down by throwing balls, bananas are sealed. That's what the monkey is after, after all. And, by the way, this is your main task. Yes, friends, the goal of the game is to knock down all the banana bubbles.

Of course, the banana balls are littered with a lot of other colorful bubbles, and to get them, you need to burst all the empty bubbles. The operation is simple when all this ball mass is represented by several large single-color groups. Then, throwing a ball of the corresponding color into each of these groups, you will burst them all and get bananas.

The task becomes more complex in stages. At the second level, for example, the mass of balls will no longer be as uniform in color as at the first level. At the third stage, the heterogeneity will grow even more, and so on. Recall that to burst a cluster of balls, you need all the balls in it to be the same color in the amount of at least two. And of course, the ball that falls into this cluster should be the same color. That is, three or more single-colored bubbles burst together.

Complete 23 levels of the game, helping the monkey to get all the bananas. But after the 23rd stage, there is an infinity icon on the diagram. What would that mean?..
