River Drift
Read full descriptionHide full description
Connect the pipes and guide the water from the source to the goal. 50 levels across five biomes. Place and turn the pipe pieces. There is no timer. The game can run offline. Each biome has its own unique challenges. Every biome looks different, and a slow soundtrack runs under all of them. The biomes are grass, forest, desert, old ruins, and a volcano. If you like connect puzzles, pipe and water games, or a calm logic puzzle, this is that.

Verdict
The clearest difference is in-app purchases: Zen Logic Pro at none against River Drift's 3. Zen Logic Pro also leads on ads (none vs shown). On price, update cadence, device support and iOS requirement there is nothing between them.
