What Is CoreBall?
CoreBall (also known as Stick Pin or Ball Pin game) is a precision timing game where a ball spins around a central core. Your goal is to shoot pins into the core by clicking or pressing Space — but you can never let two pins touch. As the core spins faster and fills up with pins, finding the right gap to shoot becomes increasingly difficult.
How to Play
Click or press Space to fire a pin toward the core. Each level gives you a set number of pins to embed. Clear all pins without a collision to advance. The core speeds up and may change direction as you progress through levels.
Difficulty Modes
Normal — speed ramps gradually every 5 pins. Direction reverses at level 10+. Good for learning the rhythm. Hard — faster base speed, earlier direction changes, tighter pin gaps. Chaos — random speed bursts, unpredictable reversals, and occasional double-speed windows. For experts only.
The 100-Level Challenge
CoreBall on ReflexForge has 100 progressively harder levels. Each 25 levels marks a major difficulty jump. Reach Level 100 and complete the full challenge to qualify for a feature on the ReflexForge site. Download your result card and submit it on our Discord.
Tips to Improve
Watch the existing pins, not the empty core. Your instinct is to aim for gaps but the pins tell you where the danger zones are. Shoot the moment a pin clears your firing line — hesitation is the biggest killer at high levels. At Level 50+, the core changes direction — don't shoot immediately after a reversal, wait for the rhythm to settle first.
