Aim, shoot, pop three of a color.
Gemburrow is a gem shooter puzzle. A mole miner sits in a round mine bucket and shoots cut gems from a copper launcher at a chain that rolls along a mine-cart rail track toward the nest of a sleeping baby dragon. Three or more of the same color pop; clear the chain to win, and if it reaches the nest the dragon wakes up and the level is lost. You get a finished game with menus, progress, music and sound effects, plus the complete source code to reskin, translate and publish as your own.
Chain reactions and three stars
Touch or click to aim and release to shoot; one tap on the mole swaps the gem with the one in the iron pan (right-click or Space on a computer). When a gap closes and the colors at both ends match, they pop too. Gap shots, streaks and the free track left at the end add points, and each level gives up to three stars. Each gem color has its own cut, so the pieces can be told apart without relying on color alone.
5 worlds, 50 levels
Copper Tunnel, Crystal Grotto, Mushroom Hollow, Frost Cavern and Dragon's Hoard, ten levels each, every world with its own background, trackside props, track colors and mole headwear. Tracks go from ovals and spirals to a figure eight with a bridge and levels with two tracks; tunnels hide the gems and frozen gems break free only when their neighbours pop.
Four power-ups and four special gems
Freeze stops the chain for a few seconds, rockets pop five gems at once, the hammer smashes where you tap and the rainbow gem matches any color. In the chain, a bomb blasts its neighbours, lightning clears its whole color, the snail slows everything down and rewind rolls the chain back.
A guided start and 14 languages
Level 1 is a guided tutorial: the mole explains each step while a hand shows where to tap, and a short tip introduces each new piece. The interface comes in English, Portuguese, Spanish, French, German, Italian, Dutch, Polish, Turkish, Russian, Indonesian, Japanese, Korean and Chinese. The settings have music and effects volume, vibration, less motion and full screen.
Yours to customise
Plain HTML, CSS and JavaScript with no build step and no dependencies: upload the game folder to any static host and it runs in portrait and landscape on phones, tablets, desktops and ultrawide screens. The full editable source comes with tests for the rules, every level, the 14 languages and the save key, an illustrated guide in 14 languages and a customisation guide with numbered screenshots. No ads, no store, no ranking and no server.
Don't wake the dragon
When the chain gets close to the nest the track slows down, the edge of the screen pulses and the baby dragon wakes up. Levels unlock one after another, locked worlds can be previewed, the first 3-star win of a level rewards an extra power-up, and after level 50 a Journey Complete screen adds up the stars and scores.
