ZEN is an innovative puzzler with original gameplay that combines precision, reaction and inventiveness. Your goal is to guide the ball though a labyrinth towards the gates, avoiding collision with sparkling blocks. Move the ball using combination and sequence of waves, the number of which is limited for each level, so make sure to choose the shortest way. And cut corners. "The first few levels are easy, but, by level eight or nine, the game gets challenging quickly." - www.touchgen.net

Verdict
The clearest difference is price: One Stroke Brain Puzzle at Free against ZEN's $0.99. ZEN's advantage is ads (none vs shown) and update cadence (every 11 months vs every 55 months). On in-app purchases and device support there is nothing between them.
