Case Study: ZeptoLab Achieves 50%+ Day 1 Retention with PlaytestCloud

How Zepto Lab used PlaytestCloud to increase D1 retention by 50%

Zeptolab, the global mobile game company behind the Cut the Rope franchise, used PlaytestCloud to diagnose a critical challenge with their new game, Om Nom: Run. Their internal tests were biased, and they discovered through a PlaytestCloud single-session playtest that the game’s difficulty curve was broken, causing most players to fail within the first five seconds.

The solution involved an iterative six-month process where Zeptolab used PlaytestCloud to continuously test and rebalance the game's levels. This allowed them to decrease early obstacle density and perfect the progression. The measurable results were a 50%+ increase in Day 1 retention and 5 million downloads within the first month of launch.
