Four simple steps to get started. The real challenge is beating your own high score.
Move your mouse or finger to guide your glowing trail across the game arena.
Cross your own trail to create an enclosed area — this is how you capture enemies.
Any blue orbs inside your loop are captured and destroyed, earning you points.
Red bomb orbs drain your energy if enclosed. Avoid them or plan carefully!
Four distinct enemy types keep gameplay fresh and challenging. Learn each one to master the game.
The standard enemy. Stationary blue orbs that pulse with energy. Enclose them to earn 30 points each. They explode over time if not captured.
SAFE TO ENCLOSEDangerous red orbs that drain 30 energy points if enclosed. They look similar to normal orbs but glow red. Avoid enclosing them at all costs!
AVOID ENCLOSINGGreen orbs that move around the arena after a short delay. They're harder to enclose but worth the same points. Appear after 2 minutes of gameplay.
TRICKY TO CATCHThe most dangerous enemy — an orange bomb that moves around the arena. Enclosing one drains massive energy. These appear at higher difficulty levels.
