Demolition Ball

Suit up, grab the wrecking ball, and clear the site — one contract at a time. Demolition Ball is a physics-powered brick breaker with a full construction-site attitude. If you grew up on classic breakout and brick-breaker games, this is that same addictive paddle-and-ball formula — rebuilt with real physics, chain combos, and a demolition crew's sense of humor. Aim your wrecking beam, launch the ball, and smash through red brick, cracking concrete, and indestructible steel to clear every structure on the blueprint. SMASH THROUGH VARIED STRUCTURES • Red brick crumbles in one hit • Concrete takes two hits to crack • Steel never breaks — bounce off it, work around it • TNT crates trigger chain-reaction explosions • Mystery equipment crates always drop a power-up CATCH FALLING EQUIPMENT Keep an eye out for power-ups tumbling down from broken bricks: • WIDE BEAM — bigger paddle for easier catches • MAGNET — the ball sticks on impact, tap to release on your terms • TRIPLE BALLS — three wrecking balls demolishing at once • LASER CUTTER — tap to fire twin bolts through anything in your path • SLOW-MOTION — every ball moves 30% slower for precision shots • EXTRA HARD HAT — restores a life • Watch out for the shrink ray — it's not on your side AN ENDLESS CAREER IN DEMOLITION Clear the campaign one contract at a time, earning up to three stars per site by finishing with your hard hats intact. Contracts keep coming — levels scale forever, with denser brick structures, tougher steel, and new site layouts the further you go. Need a faster shift? Jump into Endless mode and clear wave after wave of bricks for as long as you can hold the line, with hazards and speed ramping up every round. Lost your last hard hat? Call in the backup crew for one more shot — no contract has to end early. WHY BRICK-BREAKER FANS STICK AROUND • Real momentum and bounce-angle physics, not scripted ricochets • Hundreds of hand-built and procedurally generated brick layouts • Combo scoring that rewards fast, precise breakout play • A construction-site theme that turns a familiar genre into something new FAIR MONETIZATION Play free, forever.

Verdict
The clearest difference is ads: Quantum at none against Demolition Ball's shown. Demolition Ball's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 17.6). On price, update cadence and in-app purchases there is nothing between them.
