Number Route

Number Route is a free browser number puzzle from BrainiLab. Each route gives you four numbers and a target. Keep the numbers in their original order and choose addition, subtraction, multiplication or division between them. Calculations run strictly from left to right, so this is a game rule rather than ordinary written order of operations. Use every number to reach the target. Anytime play offers ten routes, and a guided practice example is available before starting. The instructions are in English. There is no installation or account requirement to play. The game was developed with AI assistance and human direction. Play on the original BrainiLab website.
