Card Selection

After each wave, you'll be offered cards to choose from. Pick a new tower to unlock, or a bonus to boost your defenses. Choose wisely — some bonuses come with trade-offs!

Some cards carry a risk of tower devouring — a worm may devour your towers when you pick that card. Towers are chosen at random, never two side by side. Before wave 6, cards show a 0% chance of tower devouring to protect your early progress.
