About FireStack

You drop falling firecrackers onto a grid and merge matching ones to create bigger explosions in FireStack. Each time two identical crackers touch, they combine into the next size up, clearing space and adding to your score. The challenge is deciding where to place each piece as it falls – one wrong move can fill your grid too quickly and end your run. The game continues as long as you have room to drop new crackers, so planning ahead is key. Larger merges earn more points, rewarding you for setting up chain reactions and keeping your playing field tidy. Available on Poki Games, this casual puzzler tests your spatial reasoning and quick thinking as the pace gradually picks up.
