About
Build the ultimate rocket. Launch it. Watch the fortress crumble.
Kapult is a fast, satisfying physics game where YOU craft the weapon. Fuse parts on the crafting grid into a one-of-a-kind rocket, fire it at towering fortresses, and bring them down in a shower of rubble. The better your build, the bigger the boom.
• CRAFT YOUR WEAPON — combine parts into powerful rockets. Every build hits different.
• ONE BIG SHOT — aim, launch, and watch the slow-mo destruction.
• SMASH FORTRESSES — knock down detailed castles that crack, catch fire, and crumble.
• DAILY CHALLENGE — everyone plays the same run each day. Top today's leaderboard.
• GLOBAL RANKS — climb the worldwide leaderboard and become a Kapult King.
• CHALLENGE FRIENDS — send a link, same forts, same parts. Settle who's best.
Easy to pick up, hard to put down. How far can you get?
Build it. Launch it. Smash it.
