About

Asteroid Crash

Features
Read full description

Asteroid Crash hands you a rim-riding cannon, a well full of spinning gravity, and one rule of the trade: rock only pays when it breaks. The well's gravity direction rotates. The rubble pile you just built tumbles along the wall as "down" sweeps the circle, and your cannon rides the rim above it all. Drag to aim, release to launch a big asteroid into the churn โ€” the harder and cleaner it hits, the more it shatters. Every crush steps the rock DOWN the ladder: Boulder to Rock, Rock to Fragment, Fragment to Ore, Ore to Dust. Dust banks itself as score. Nothing grows. Everything breaks. โ€ข The shatter ladder: five tiers from Boulder to Dust, split by impact speed and angle โ€ข Hazards that change your aim: iron-core asteroids take two clean hits, volatile pockets blow the pile apart, crystal seams pay a precision bonus โ€ข CORE BREACH: crush five asteroids in one revolution and the well itself quakes โ€ข A career, not just a score: climb from Prospector to Surveyor, Foreman, Chief, and Legend across five zones โ€” Rubble Belt to Event Rim โ€ข One daily seeded well, identical for everyone, with trophy tiers and a spoiler-free share card for bragging rights โ€ข One-finger controls: drag anywhere to aim along the rim, release to fire โ€” no timers, instant restarts โ€ข Everything runs on your phone โ€” fully offline, no account, nothing collected The well spins. The rock breaks. Bank the dust before the mouth jams.

SoulStack

SOULSTACK โ€” a necromancer auto-battler of stacked souls. You were a master of death, stripped of power and cast into the Pit: an endless tower of the dead. But every foe you slay rises to serve you. Recruit them. Fuse them. Weave a legion that multiplies โ€” and climb. โ—† A LEGION THAT COMPOUNDS Draft undead, beasts, mages, and rogues into your warband. The power isn't flat stats โ€” it's synergy. Line up the right tribes, roles, and Authorities and your army doesn't add up, it MULTIPLIES. Find the engine, break the wall. โ—† CLIMB THE ENDLESS PIT Every run is a fresh draft. Scout the floor ahead, counter it, and climb โ€” the dead grow without limit as you rise. Fall, and you return to Level 1โ€ฆ but the servants you raised carry into the next life. Rise again. โ—† COMPETE WITH FRIENDS โ€” ON YOUR TIME Conquer the Pit and set your army to guard your star. Then raid your friends' stars across a season of standings. It's all ASYNC โ€” no live matches, no waiting, no always-online. Take a turn whenever you like; the war continues without you. โ—† FAIR BY DESIGN Premium โ€” buy once. No ads. No gacha. No pay-to-win: the unlock sells the full climb and the collection, never power. Competition is normalized, so skill wins, not spending. โ—† THEORYCRAFT-DEEP Deterministic combat and simulation-tuned balance reward mastery over luck. Dozens of units, items, and Authorities to combine โ€” the deeper you read the synergies, the higher you climb. Raise the dead. Stack the souls. Climb.

Verdict

The call

The clearest difference is in-app purchases: Asteroid Crash at none against SoulStack's 1. Asteroid Crash also leads on update cadence (daily vs every 2 weeks). SoulStack's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price and ads there is nothing between them.
