Number blocks will attack you in Unblock on every level. They appear from above and their number increases, they move closer, filling the field. The triangular icon at the bottom is your ship or plane from which you will shoot at the blocks. You can move in a horizontal plane. Catch drop-down bonuses, they will allow you to fire several projectiles simultaneously in the form of a fan to increase the area of impact on blocks. The numbers on the blocks indicate their strength. The higher the number, the more shells you need to spend on it in Unblock.
