A mining run, a profitable trade route, or one more pirate to take down. What does your ship need next? Driftbound is an idle space RPG where you start with one ship and work your way from the safe core worlds to the lawless rim. Mine, craft, trade and fight through a procedurally generated universe. Set your ship to work, close the game and come back to see how it went. MAKE A LIVING IN SPACE Mine asteroid belts, harvest gas, scan for salvage and turn raw materials into better gear. Stations have their own economies, so a full cargo hold is worth more if you know where to sell it. Take delivery jobs, follow leads from station residents, or carry contraband past customs if you're willing to risk your cargo. PICK A SIDE IN THE FACTION WAR Earn a faction's trust and take its oath. Complete three Orders a week, climb ten Merit ranks and choose a doctrine that suits how you play. Patrols, deliveries and scans help push your side's front. Watch systems change hands, hunt named captains, intercept convoys and work towards a Warlord's stronghold. Special war encounters wait for you to start the fight. BUILD A SHIP THAT CAN HANDLE IT Fit weapons, shields, engines and cargo upgrades. Craft equipment, collect rare modules and choose perks for the jobs you enjoy. Fight pirates with automatic weapons, then decide when to fire a missile, repair or get out. Better gear opens up tougher places with better salvage. THERE'S MORE AFTER YOUR FIRST RUN Follow the campaign and faction stories, hatch space pets and collect outfits and trophies. Re-enlist to earn Renown for permanent Admiralty upgrades. Push into harder Deep Runs or descend into the Undertow to see how far your build can take you. Your pets stay with you when you re-enlist. PLAY AT YOUR OWN PACE Travel, work, pet incubation and ordinary combat can progress while you're away. The return report shows what happened, and you can carry on with a mission or change your plans. Offline play works without the online features. Connect when you want to trade with other players on the Exchange, see nearby pilots or try a friendly duel. No ads, in-app purchases or subscriptions. No account signup required. Pixel-art ships and worlds, adjustable text size, and nine languages: English, Spanish, Portuguese, French, German, Italian, Czech, Bulgarian and Simplified Chinese.

Bitmerge: merge data, compound income. Drag matching tiles together and watch them fuse up an exponential chain: bit, nibble, byte, and onward toward the AI core. Every tile on the board earns for you, every second. Higher tiers earn far more than the pieces they're made of, so merging always pays. MERGE UP THE CHAIN Two identical tiles become one of the next tier. Simple to do, hard to put down. Each merge frees board space and multiplies your income. EARN WHILE YOU'RE AWAY Your board keeps generating while the app is closed. Come back to banked progress, reinvest, and push the chain higher. RECOMPILE INTO QUBITS When spawn costs wall you out, recompile: collapse your run into qubits, a permanent income multiplier that makes every next run faster. The reset is always free and always your choice. BUILD THE MOTHERBOARD Deeper still: escalate for kernels, then reboot into the motherboard. Drag its parts around a grid, and the closer linked parts sit, the more they pay. Every new peak of blocks earns points to drop as boost tiles on the CPU, the GPU or RAM, and the layout you build keeps paying however high you climb. AUTOMATE THE GRIND Earn daemons that spawn, merge, defrag and even recompile for you, and keep working while you're away. Set their levers and leashes; the machine plays itself exactly as hard as you let it. NEVER STUCK A full board is never game over: a fresh spawn merges straight onto its match, more board space is earned in-game, and the recompile is always free. You can always recover without paying. That's a design rule, not a promise. NEON BY DESIGN Strict minimalism: clean lines, high contrast, and a living circuit-board background that ripples like water as you drag. Tiles are chips that grow with their tier (more pins, denser dies, extra electrons in orbit) until the top of the chain runs white-hot and the AI core turns prismatic. EARN LIMITED SKINS Timed events arrive on their own schedule and run on a save of their own, with their own board rules and their own prize. Finish one and the skin is yours for good, wearable the moment you win it. DRESS THE BOARD Four optional skins redraw the whole board, not just its colours. Blueprint is two sheets in one purchase: Cyanotype and Vellum, your board drawn in ink on paper. Clockwork is a brass movement whose wheels turn at the speed your tiles earn. Orbital puts your tiles in orbit as stations, and a drag bends the starlight around your finger. Neural turns your tiles into neurons, and every merge fires a spark along the synapses. Preview any of them on your own board for 60 seconds before you buy. CLIMB THE BENCHMARK Game Center leaderboards rank your live balance as a benchmark index: spend and you drop, bank and you climb. A free-only division ranks players who never bought power. NO ADS, EVER No banners, no interstitials, no ad SDKs. Bitmerge is free to play with a few optional purchases; nothing you must buy to keep playing. Download now and merge your first bit.
