About this game

Stack Smash is a satisfying physics knockdown game where you fire a cannon at towers of crates, jars, barrels, and blocks. Tap where you want the ball to go, watch the stack crumble, and clear every target before you run out of cannonballs. Easy to pick up, tricky to three-star, and wonderfully crunchy every single shot.

Ready to fire? Download Stack Smash now and knock down your first tower!

Every level gives you a limited supply of cannonballs and a stack of targets balanced on platforms. Glass shatters at a touch, wood needs a solid hit, metal and stone take real force, and TNT blows everything around it sky-high. Aim for the weak spot, let physics do the rest, and finish with balls to spare for the full three stars.

💥 HOW TO PLAY
★ Tap anywhere to aim and fire a cannonball at that spot.
★ Knock every target off its platform to clear the level.
★ Spend your cannonballs wisely, each level gives you a fixed supply.
★ Finish with balls left over to earn two or three stars!

⭐ KEY FEATURES
★ Endless Levels: 100 hand-built stacks, then freshly generated towers that never run out.
★ Real Physics: Every crate tumbles, bounces, and shatters the way it should.
★ Six Materials: Glass, wood, metal, stone, diamond, and explosive TNT, each with its own feel.
★ Chain Reactions: One well-placed ball into a TNT barrel can level the whole stack.
★ Star Ratings: Replay levels to beat your best and collect every star.
★ Second Chances: Out of balls? Grab a few more and finish the job.
★ Easy to Play: One-tap controls and short, punchy levels. Great for all ages.
★ Free to Play: Download and play for free.

Whether you have thirty seconds or a whole evening, Stack Smash is the perfect stress-relief game. Line up the shot, pull the trigger, and enjoy the crash.
