One more wave. One bigger jump. One new personal best. Carve through turquoise water, chase moving jump waves and dodge reefs, sharks and swooping seabirds. Reef Run is a colorful 3D arcade surfing game you can pick up in seconds: hold either side to turn and release to coast. 35 COASTS. YOUR KIND OF CHALLENGE. Choose relaxed water, fast runs or the new Breakwater Gauntlet: an expert coast with rock jetties across your path. Catch the approach wave to jump clear, or carry a reef shield through the barrier. Fresh layouts keep familiar coasts surprising. GO FASTER. CATCH MORE AIR. Longer runs build speed and pressure. Follow pearl trails around reefs, land automatic air tricks and thread flow gates for bonus points. Board powers add speed bursts, score bonuses, magnets and shields. FIND YOUR SURF STYLE.

Mix your favorite look, from tropical colors to lightning, rainbows and comets. 100 LEVELS OF REWARDS. The permanent Wave Pass rewards surfing, collecting pearls and landing jumps.

Core gameplay needs no game account or subscription. Ads may appear after every two completed runs; an optional rewarded ad offers one second chance per run when available. Ads, purchases, restores and Game Center require internet access. Six optional one-time packs each include a board with enhanced powers, top, shorts, hat, trail and character.
