Drag and combine cosmic objects on a 5×7 grid to evolve them through 12 tiers of celestial bodies — from cosmic dust to a fully-formed galaxy. A relaxing single-player puzzle for iPhone & iPad.
Drop in for two minutes or two hours — the energy system regenerates while you're away, so there's nothing to grind.
Smooth, intuitive interactions with cascading chain reactions when matches collide.
No artificial walls — energy refills on its own clock. Play in short bursts or long sessions.
Fresh objectives every day plus a 7-day reward streak that scales with consistency.
Reset your universe to unlock permanent multipliers — the deeper meta-loop for puzzle veterans.
Neon, Retro Pixel, Aurora, Void — change the look of every object on the board.
Every cosmic body you discover is logged — chase 100% completion across all 12 tiers.
Objects keep spawning while you're away. Come back to a board full of new merges.
Every cosmic body is drawn by code at runtime. No image assets, no downloads, no bloat.
Cosmic Merging is a single-player offline game. No account, no analytics, no advertising SDKs, no IDFA. Every grid, gem and prestige counter lives in local SwiftData storage — and only there. Read the full Privacy Policy.
Free to play. Optional gem packs and cosmetic skins through Apple's StoreKit.
No ads ever. Optional in-app purchases for gems and skins.
No. The game is fully offline. The only network activity happens through Apple's StoreKit when you make an in-app purchase. There is no account, no cloud save, no telemetry.
Any iPhone or iPad running iOS 17 or later. The game uses SpriteKit + SwiftUI and is optimized for both portrait phones and landscape iPads.
All progress (grid state, tier discoveries, gems, daily streak, prestige counters) is persisted locally with Apple's SwiftData framework. Uninstalling the app removes everything; there is no cloud backup.
Once you reach high-tier objects, you can trigger a "Big Bang" to reset your board in exchange for a permanent multiplier on a future stat. It's the deeper meta-loop for players who want long-term progression beyond a single playthrough.
No. Gem packs and skin packs are direct purchases — you see exactly what you get. There are no random rewards, no spins, no chance-based mechanics tied to real money.
