Play Q Billion (Japan) Online
You're a tiny mouse shoving numbered blocks around, trying to turn them all into 1s—until they start multiplying and subtracting when they touch, and suddenly your neat little puzzle turns into chaos.
Q Billion is a 1989 Game Boy puzzle game from Jaleco, a company known for a range of arcade and console titles. It arrived early in the handheld's life, a time when developers were still exploring what worked on that small, green screen. This one stands out for its numerical, almost mathematical, approach to block pushing.
You control a small mouse, pushing numbered blocks across grid based stages. The goal is to reduce every block on the screen to a value of 1. The core mechanics involve making blocks collide; when two blocks of the same number touch, they combine into a single block with a doubled value. Conversely, pushing a block into one with a different number causes the first block to subtract its value from the second. This creates a chain reaction of calculations that you must carefully manage. The pacing is deliberate, requiring forethought, but a wrong move can quickly spiral the puzzle into unsolvable chaos. It feels like conducting a fragile, unpredictable equation.
