Candy for Om Nom. Om Nom wants every sweet on the board, and you are the one doing the shooting. Om Nom Bubbles is a candy bubble shooter played against a ticking timer, so clearing fast matters as much as clearing well.
The aiming laser. A laser line shows where each shot will travel, which lets you line up angles before you fire. Use it every time rather than shooting on instinct.
Power-ups against the clock. Big scores unlock power-ups. Some put extra seconds back on the countdown, others set off large explosions that wipe out a whole area of candy.
The fireball streak. Land ten hits in a row and you earn a fireball that burns straight through the bubbles. Keeping a streak alive is therefore worth more than one lucky shot. The plain, candy-free version of the format is Bubble Shooter Classic.
