Drill deep, strike it rich – and make sure you have enough fuel to get back up. Drillbound is a portrait mining game with a space twist. Pilot DRL-9, a small salvage robot, across five alien planets, dig for rare ore and decide on every run how deep you dare to go. DIG DEEPER, EARN MORE • Drill down and sideways through layered rock • Rare ore is worth up to 2.5× more in the depths • Sell your haul for credits or bank it for upgrades MIND YOUR FUEL • Every meter down costs jetpack fuel to fly back up • Hard landings damage your hull – brake in time • Run dry and your cargo is lost UPGRADE YOUR ROBOT • 5 upgrade tracks with 10 levels each: drill head, energy cell, cargo bay, hull plating and fuel injector • Dynamite, fuel canisters, repair kits and return beacons for risky runs • Bounties pay extra credits FIVE ALIEN WORLDS Rust world Ferrux, ice planet Cryon, volcanic Pyra, toxic Venox and crystal world Prisma – each with its own ores, stronger gravity and harder landings. Complete deliveries to unlock the next planet and bring DRL-9 home. FAIR AND OFFLINE • World 1 is completely free • One-time unlock for the full game – no subscription • No ads, no premium currency, no pay-to-win • Plays fully offline, made for one-thumb portrait play

Verdict
The clearest difference is ads: Drillbound at none against Elf Castle's shown. Drillbound also leads on update cadence (every 2 months vs every 6 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.
