The host of the show "Protect & Keep!" throws down a challenge: he'll smash, burn, and blow things up — and you build the defense. Raise walls of wood, brick, steel, and titanium around a valuable prize and survive waves of attacks: fire arrows, catapults, tanks, acid rain, and laser beams.
Every material works differently: wood is cheap but burns, sandbags absorb explosions, rubber bounces cannonballs right back, and only steel will stop bullets. Study the attacks, plan your defense, and spend your budget wisely — the more intact the prize, the more stars and coins you earn!
How to play
1. Study the wave cards — they show which attacks are coming and from where: impact, explosion, fire, or penetration.
2. Build a defense around the prize with the budget you're given: pick a material at the bottom and tap the grid cells.
3. Match materials to the threat: against fire — stone and water tanks; against explosions — sandbags and concrete; against bullets — steel. Wood burns!
4. Hit "Fight!" and survive all the waves. Between waves, repair blocks and extend your wall — repairs are cheaper than building new.
5. The more of the prize's value you save, the more stars and coins you get. Spend coins on boosters and skins.
6. Clear all the levels and unlock the endless siege — set records and climb into the ranking of the best defenders!
