Use the mouse to guide your snake’s direction in SLITHER IO. Moving the cursor steers the snake, and clicking the mouse activates a speed boost to outmaneuver opponents, but it slightly shortens your length.
The game primarily features a single-mode MMO experience where players compete against others online. There are no separate levels, but the challenge lies in surviving and growing as long as possible.
