ROLL
ROYALE

1. Aliens descend in three straight lanes from three UFOs. Its beam shields new arrivals until they reach the open battlefield. Your free Gunner can handle wave one.
2. Tap a tower, then an empty slot to move, a different tower to swap, or a glowing match to merge. Five front slots fire; the 15 storage slots and recovery never fire.
3. Roll, upgrade, move or merge only while planning. Two same-kind, same-rarity towers become one next-rarity turret, capped at Special. Press Defend when ready.
4. Tap 1× / 2× speed during defense. Pause freezes all combat timers. Dragon flights stay at normal cinematic speed. A new enemy arrives every 10 waves; longer waves keep sending reinforcements. Pause never unlocks the shop. Resume when ready.
5. Loss or closing during combat returns to your pre-wave plan. Rewards count only after a wave is won. Continue through all 100 waves. Bosses appear every five waves.

Keyboard: Tab between controls; Enter or Space activates buttons. No dragging, sound or fast tapping needed. Coins always collect automatically.
