The way this booster works can cause some confusion at first, but don't worry—it's actually quite simple 🤗

The Double Paper Planes booster ✈️ can be activated before the start of a level. Just tap its icon in the window before the start. This booster does not show up on the field at the beginning of the level but you'll automatically get twice as many Planes in the level after it's activated. And if you match two Planes together, you'll launch five planes, each with its own target 🎯
