Gemlock Quarry

Mine both ore blocks and unlock both treasure chests before the gem deck or shaft space runs out. Tap any column to drop the next gem. An incoming gem fuses only with an identical color and value at its first impact; the doubled value blasts side-touching ore for that much damage. A chest opens when its neighboring cells contain both amber A and blue B gems. Broken ore and opened chests disappear, letting unsupported gems fall without extra fusion. Hold stores the next card in a one-card reserve; Toggle reserve chooses whether the next drop uses that reserve or the deck. Ore blocks can obstruct a chest’s second neighbor, so mine access before feeding its color key. Keyboard: Tab and Enter/Space operate buttons; R restarts.
