Digline is a relaxed and easy to learn drilling game where every descent is a gamble between progress and risk, and the real reward lies deeper underground. Start each run in your workshop, pick your setup, and head down with limited fuel and a scrappy rig. Carve your path through shifting layers of earth, decide what to collect, and choose what to upgrade and what to trade before everything runs out. Each dive reveals new materials, rarer finds, and unexpected patterns beneath the surface. What begins as simple digging gradually turns into a careful balance between exploration, efficiency, and timing. Back at the surface, refine your strategy and improve your runs: • Upgrade your drill, fuel capacity, and efficiency • Unlock new materials with higher value and deeper placement • Optimize routes to maximize each descent Progress builds steadily, but every run carries tension. Go too safe and you leave value behind. Push too far and risk losing it all. Shape your own rhythm underground: short and efficient runs, deep high-risk dives, or a steady climb toward mastering what lies below. Top 10 casual game in the US and UK, Top 5 in Germany, Norway, and others. Come join the fun! What starts as a simple search for resources gradually becomes something stranger. Your old tunnels remain, your map expands over time, and the underground begins to feel less random and more like a place with its own history. Digline is designed to be easy to pick up, fun in short sessions, and rewarding over the long term. Quick digs, short descents, tons of relaxing fun. Features: • intuitive one-finger portrait controls • short runs that fit easily into a minute or two • persistent tunnels and a map that grows with each expedition • multiple underground regions with different materials, hazards, and surprises • resources to gather and use for crafting upgrades, and better preparation • a workshop that turns each successful run into permanent progress • a market system for trading what you bring back • progression that builds across many sessions, not just a single run • a calm, cozy atmosphere with a sense of discovery underneath it • no ads, no in-app purchases, and no pay-to-win systems • achievements and Daily Dig leaderboard competition The deeper you go, the more the mine will reveal.
