Six calm games made with photographs of opal, turquoise, paua and more. Follow the trail to where each stone was found. No ads, nothing to buy. Gem Trail is a set of six calm games made with photographs of Oli&J gemstones: Australian opal, turquoise, variscite and rhodonite, New Zealand paua and more. THE GAMES • Crystal Arena (new): plant resonance charges, crack the host rock and free the stones, outwit the black-opal guardians, then reach the glowing arch. • Oz Storm: thrust, turn and blast through a drifting field of stones. Ride out the red dust storm, keep clear of the Opal Vortex and fend off alien sentinels. • Stone Drop: drop stones into a jar; two the same merge into the next stone on the trail, from beach sand to an Oli&J setting. • Stone Finder: lift stones off a stacked pile into a seven-place tray, where three of a kind fuse. Clear the pile before the lantern burns down. • Field Match: swap stones into lines of three, crack the host rock, fill commissions and chain into Fever. • Stone Stack: fit falling stone formations, clear rows and shatter veins of eight before the rock rises. THE ORIGIN TRAIL Visit the places the stones come from, from the opal fields of Coober Pedy and Lightning Ridge to the cold water off Stewart Island. DAILY QUESTS Three short quests a day: play a game, earn 30 points and visit a place on the trail. Finish all three to unlock a 10% code for your order at oliandj.com. PRIVATE BY DESIGN No account, no ads, no tracking and nothing to buy. Your scores stay on your phone, and the games work offline. An optional daily reminder, if you turn it on, is scheduled on your phone too. Gem Trail is made by Oli&J. See the collection at oliandj.com.

A sixth game: Crystal Arena. Plant resonance charges, free the stones and reach the glowing arch. After a game, discover real stones from the mines you've explored. Keep score & exit: end a run from the pause menu and keep your points. Louder game sounds, and a smoother fast drop in Stone Stack.
