Suumtiply, a zippy Windows 10 math challenge, is today's AdDuplex HERO App

If enjoy fast-paced math puzzles, then Suumtiply is a Windows 10 game worth a look. Available for Windows 10 Mobile, the game challenges your skills at addition and multiplication to see how many puzzles you can solve before the game timer strikes zero.

Suumtiply is also today's HERO App — a promotional campaign for Windows Phone and Windows developers on the AdDuplex Network. The campaign partners AdDuplex with AppDeals, TechRewards{.nofollow} and Windows Central to deliver a host of benefits to the top apps and games each month. Our role in the HERO App campaign is to offer a little exposure to these titles by sharing them with you, our readers.

Suumtiply greets you with a modest primary menu that has options to jump into gameplay, remove the ad support ($0.99), restore any in-app purchases and view other games from the developer. I did find the in-app purchase support for Suumtiply to be a little on the finicky side and took several attempts before the game successfully loaded the option to make a purchase.


When gameplay begins for the first time, Suumtiply offers you a very brief tutorial that covers the mechanics of gameplay. The game presents you with a sum and several number variables lining the bottom of the screen. It is your job to combine the numbers to match the sum.

Adding the number variables is accomplished by tapping the variables you want added together. For example, if you have the sum of 5 and the variables 2,3 and 8 you would tap the 2 and 3 to solve that puzzle.

Along with matching the sum by adding the variables, you can also match the sum by multiplying the variables. Multiplication is accomplished by tapping/holding a variable and sliding it to another variable to multiply.

The challenge of Suumtiply comes into play with the game timer. Each puzzle affords you about twenty-seconds to solve the puzzle and the timer is illustrated by a ring around the targeted sum that slowly fades away. As you solve puzzles, a little time is put back on the clock — but the further you progress in the game, the more difficult the puzzles become. The number of variables available increases and some puzzles require the combination of addition and multiplication to match the sum.


As you add or multiply numbers, the working sum appears beneath the target sum. As you tap or slide a number, it will be replaced with another number variable. If you are unable to match the sum with the numbers available, the puzzle resets and you lose valuable time on the game clock. It also appears to be a limit of five moves on each puzzle. If you add or multiple more than five numbers, the puzzle resets and again, you lose valuable clock time.

The ultimate goal of Suumtiply is to solve as many puzzles before the game clock hits zero. Scoring is displayed across the top of the gaming screen, along with your high score.

The free gaming title is available for Windows 10 Mobile, as well as Windows Phone 8.1. Suumtiply may not be the most eye-catching puzzle games, but the pace of play makes the gaming title a decent option when you have a little time to kill.
