The mobs are legion and they cross the portal by ten.
Use the ball to push them back before they cross the red line.
You want to crush them: use the ball.
There are too many of them: use the maxi ball.
They are too fast: immobilize them with the frozen ball.
They're too strong: Crush them to dust with the fireball.

All means are good to close the portals.
It's up to you to find the one you want with the coins won during the games.

Level after level, the cups you win will show everyone that you are the strongest.

Good game.
