Sort shells on a shoreline belt as the tide carries patterned finds and plain stones left to right. Watch the target label at the top, then tap only matching shells before they wash past the edge. Stones and wrong patterns cost lives, and letting true shells slip away also hurts your run. Speed climbs on later shores while labels change more often and the belt grows crowded. Collect the quota of correct shells to clear the beach run and face denser tides with faster belts and trickier patterns. Stay focused on the label, ignore look-alike stones, and finish the sorting quota before the tide grows too fast.
Tap the labeled shell patterns on the tide belt; skip plain stones.
