Ripple Path

Ripple Path is a calm koi pond puzzle for phones. Each pond is packed with winding koi, and a koi can only swim the way its head points. Tap one, and if its lane is clear it glides out of the pond. If another koi is in the way, it bumps back and the blocker flashes, so you see what must move first. Every bump costs a lotus, so plan your order. Along the way you free sea creatures, like a crab that snips seaweed and a turtle that pushes coral. There are 500 ponds and a Daily Pond, and you can play offline. Free on Google Play.
