Blocks with numbers fall from above, and your task is to catch the right ones to build your factor step by step.
Every good choice pushes you forward. Every mistake pulls you back — but never ends the run.
There is no rush and no countdown.
Progress depends entirely on how well you read the flow and react to changing patterns.
As levels advance, the pace increases, new block types appear, and holding your progress becomes a challenge of focus rather than speed.
Smooth motion, bold numbers, and energetic visual feedback turn simple actions into a satisfying rhythm.
Stack the Factor is designed for players who enjoy calm intensity and the feeling of earning every step forward.
