Idle Ball Crusher

Smash bosses and earn offline — crystals pile up while you sleep. Idle Ball Crusher blends ball-smashing boss combat with deep idle progression. Speed, angle, and mass all affect your hit — upgrading your ball actually feels different. Each boss changes how you need to think, and every improvement shows up in your next collision. ▶ EARN WHILE AWAY — Up to 4+ hours of offline crystals accumulate automatically. Return to a pile of resources every session. Double it with one optional rewarded ad. ▶ SMASH 12 UNIQUE BOSSES — Each one demands a completely different approach. The Ironclad only takes damage above minimum speed. The Slime slows your ball up to −50% per hit. The Splitter divides at 50% HP. The Phantom phases in and out of vulnerability every 3 seconds. Every boss changes how you play. ▶ CHAIN COMBOS FOR MASSIVE DAMAGE — Land consecutive hits to climb NICE → GREAT → MEGA → ULTRA. Up to ×7 damage and ×4 crystals per hit at the top rank. A density-based Burst Combo stacks on top for even bigger explosions. ▶ UNLEASH 6 ACTIVE SKILLS — Speed Burst triples speed. Defense Collapse strips armor. Multi Ball launches 3 balls. Slow Time freezes the clock while keeping full damage. Critical Storm makes every hit crit. Click Frenzy maxes your click boost. Time them right. ▶ BUILD ACROSS 8 UPGRADE PATHS — Pour crystals into Speed, Size, Mass, Damage, Critical Hit, Combo Window, Offline Income, and Min Speed. Every upgrade is visible. Every upgrade matters. ▶ PRESTIGE WITH PURPOSE — When you're ready to reset, trigger a Dimension Collapse. Bank permanent Dimension Shards that carry across every future run. Each prestige multiplies your starting speed — watch the ×4.7 faster counter climb with every loop. Spend Shards on permanent upgrades that compound across dozens of prestige loops. ▶ 12 ACHIEVEMENTS — Unlock milestones that pay off permanently: bonus shards, damage multipliers, skill cooldown reductions. All carry across every run. Everything in this game is earned through your own progression. No energy system — play whenever you want, for as long as you want. No pay-to-win — every upgrade and boss is unlockable for free. No forced ads — rewarded ads are always optional, never mandatory. Download free. Start bouncing.
