Loot Island - Treasure Digger

Loot Island - Treasure Digger throws you onto a series of islands where you're basically a prospector with a shovel and a backpack. The main loop is simple: you see a map with a grid of dirt tiles, each hiding something. You click or tap to dig, and stuff pops up -- coins, gems, rusty keys, sometimes traps like snakes or falling rocks that damage your health or waste time. The satisfying part is when you hit a big gem cluster or a buried chest, and your backpack lights up with the loot counter ticking up. Each island has a name like "Emerald Atoll" or "Skull Cove," and they get progressively bigger with more layers of dirt. You start with a basic wooden shovel that breaks after a few digs, so you're constantly balancing between digging and upgrading. The real hook is the Tetris-style stacking in your backpack. Your bag is a grid, and every item has a shape -- a long bar for a sword, an L-shape for a ruby, a square for a pile of coins. You have to rotate and place them to fit everything, and if you leave gaps, you're wasting space. Later, you unlock larger backpacks and special items like dynamite (T-shape) that clears a small area when placed. The difficulty ramps up when enemies appear -- skeletons that shuffle around the map, or ghost pirates that hide loot. They don't kill you but they steal items from your backpack if they touch you, so you have to dig around them or use tools like a pickaxe to break their spawn points. Upgrades matter a lot: you can get a metal detector that highlights rare loot, a stronger shovel that digs two tiles at once, or a speed boost from drinking a potion mid-level. The most satisfying moment is when you complete a big stack in your backpack and it triggers a "combo bonus" -- extra coins for filling a row entirely. The game doesn't tell you everything upfront. For example, some tiles have hidden traps that only show up after you dig adjacent tiles, so you learn to dig in patterns. There are also map-specific mechanics: in "Volcano Peak," lava tiles appear and melt your items if you don't move them fast enough. The backpack puzzle is what makes this more than just a digging game -- you're constantly thinking ahead about shapes and rotations. It gets hectic when you have multiple valuable items in the field and your bag is almost full, so you have to decide what to drop or how to rotate a weird-shaped gem to make it fit. The loop is dig, stack, upgrade, unlock -- but the order changes based on luck and your choices.
