Pick a chemical and paint it on the right city to deal damage and earn coins.
A bot rains chemicals on your city from the left — your own chemicals can hurt you too, so aim carefully.
Tips: Sand + Fire = Glass · Lava + Water = Stone · Bombs (TNT / Nuke / H-Bomb) need heat — drop one then ignite it.
Spend coins to unlock chemicals, upgrade your brush, or build City Blocks.
Raze the enemy (90%) to advance the wave. Your city does not auto-repair — spend coins on City Blocks
to reinforce it. Level Up hardens your city (🛡 resistance climbs exponentially) and boosts coin gains.
If your city hits 90% destroyed, you lose.
