The stuff the Earth is made of
Rocks and minerals make up the whole planet, and this puzzle gathers them. You'll be finding the common rocks — GRANITE, MARBLE, LIMESTONE, SANDSTONE and SLATE — plus the minerals and gems hidden inside, from QUARTZ and CRYSTAL to a glittering DIAMOND or GEMSTONE.
Because every new puzzle reshuffles the ground, no two rocks and minerals word searches are the same. One round a backwards OBSIDIAN hides in a corner; the next a diagonal SANDSTONE appears across the middle.
How rocks form and change
Rocks are always changing, and the words are here. Some are IGNEOUS, born from MAGMA and LAVA that cools into BASALT, OBSIDIAN or PUMICE; others build up from SEDIMENT layer by layer. EROSION wears them down, a MINERAL crust lines a hollow GEODE, and deep down lies the solid BEDROCK. We've even hidden a FOSSIL and a giant BOULDER for sharp-eyed geologists.
It's a great fit for a science or geography topic on the Earth. Tracking down O-B-S-I-D-I-A-N turns spelling practice into a rock hunt.
How to play
Drag across a word, or click its first and last letter — both work. Each word you spot locks in with its own colour and ticks off the list, so you always know what's left to find.
