It has a very unique play style where you are given a target number aswell as numbers and signs which you are to use to create the target number. It starts of very easy but gradually gets more and more difficult.
Once you’ve completed the 10 preset challenges in any difficulty, keep playing with endless challenges which keeps giving you new challenges generated on the fly. The fun doesnt stop. All challenges have a time duration that is saved to let the user know how long it took to complete each challenge.
You also get to play against your friends by creating groups where everyone gets the same challenges and a time to complete them by. Whoever gets the fastest score wins a point in that group and others can try again on the next challenge. Each group has a difficulty set by the admin/creator of the group. After the point is awarded, a new challenge can be created. Groups can last forever.
