Thought math was already hard to begin with? Imagine having to solve an addition problem with three hidden numbers: (? + ? + ? = ?)! Add Three is a fun, challenging game that puts your math and memory skills to the test. No calculators allowed!

Forget algebra, trig, or calculus and start to like math again by going back to the basics! An exciting game everyone can play including adults, students, and even teachers! Compete with friends and classmates to see who the real mathematician is!

TIP: Remember … hints are your best friend. Don’t hesitate to use as many hints as you need.

Game Modes:

The classic. For a set of three numbers (? - ? - ?), calculate its sum and remember the last two numbers. The next set of three numbers holds (in order) the two numbers you were supposed to remember and the sum you calculated. Repeat the process. TIP: Use coins if you have to!

The main event. Give your brain a break from memorization and race the clock to answer simple fast-paced addition problems!!! Get as many answers as possible right in a row to increase your streak. Be careful not to lose your streak, or you’ll be in danger of losing the game! Great for practicing and assessing one’s grasp of addition.

Switch it up with multiplication!

An easier version of Add Three with only two numbers in a set.

I don’t reccomend

It’s a very hard game to play because it doesn’t explain the rules well. I only got to 1 point on every mode and couldn’t figure anything out.
