CalQ is the most challenging and addicting math-based board game of the store, and it's FREE! The goal is to solve as many target numbers as possible! How it works? Very simple, you just need combine as many tiles as possible to solve the target number. More combined tiles, more points. Each tile will score as their absolute value. Tiles can be positive (+1,+2, and +3), negative (-1,-2 and -3), multiplication (x2 or x3), and "stars", that will have big impact on boosting your final score!! Check out our two games mode: (a) Normal mode: solve as many target numbers in 90 seconds, and (b) TimeAttack mode: You vs the timer! Every time you solve a target number, you will earn time out of 90 seconds. You can keep playing for hours!!
