Box Packer
About PlayMemorize Box Packer
Route numbered blocks along the conveyor belt into the box that completes the exact target sum
Box Packer turns number bonds and mental addition into a tactile factory belt puzzle. A delivery box at the end of the conveyor belt has a fixed target capacity such as 10, 15, 20, or 50. Several number blocks are already inside the box, and one final slot on the belt is open.
Pick the number block that fills the box to its exact target capacity without an overflow. Early levels focus on number bonds to 10, while higher levels add multi-part crates and larger target capacities.
