Description by LAMBDA ALPHA WU LLC Written by the developer, not by AppBrain. Click to read.
Boundary Hold challenges your steady hand against a restless playfield. A safe zone sits near the center while the visible boundary jitters and occasionally shrinks. Press and drag to keep your ball inside the safe area at all times. Drift outside even briefly and the run ends immediately. Stay inside to earn one point per second, encouraging calm, controlled movement over panic. As your score grows, the boundary shakes more often, contracts further, and leaves a smaller safe region to defend. The tension builds quietly until one small slip ends everything. Perfect for players who enjoy steady focus and patience.
