## Math Puzzles – IF, THEN… by Viacheslav Komarivskyi FREE

__Math Puzzles – IF, THEN…__ comes from Viacheslav Komarivskyi. The object is to look at a set of numbers, find the pattern and then prove that you have cracked the code.

There are 30 levels and they get hard pretty quick. I spent way too much time on level 11.

At the moment, I’m somewhere around level 18.

## Number Chef: math puzzle app for all devices

Roope Rainisto recently contacted me about his new puzzle app game __Number Chef.__

It’s a math puzzle which requires simple adding, subtracting, multiplying etc.

The objective is to combine adjacent tiles to form the numbers at the bottom. The game essentially is about Order of Operations – typically a math concept that’s taught to 7th graders here in the U.S.

__Very Important: When any number is placed on an odd number – the two #s will get added.____When any number is placed on an even number – the even # is subtracted__.

Look at the second image. See the question mark? Whatever number is placed on that, will get cloned.

Some levels have numbers that alternate between being positive & negative.

See the bombs in the third image? I don’t know how they work, haven’t gotten that far yet!

There are 150 levels and I’ve done about 45. Number Chef is FREE. So do give it a chance.

## Chisla – Math puzzle and brain teaser with cool arithmetic challenge by Anton Boyarkin

__Chisla – Math puzzle and brain teaser with cool arithmetic challenge__ is a point scoring math puzzle app game. The object is to tap on the numbers that add up to the target at the top center of the screen.

Here’s where it gets interesting.

In the Normal mode: tiles disappear when you use them. However, when the tiles in a single row are all used, new ones will pop up to replace them. __You always need lots of numbers in this game__.

In the Advanced mode: tiles can be used 3 times before disappearing. Again, when all the tiles in a single row are gone, new ones will come to life.

I forgot to mention: there is a 15 second time limit. Finding numbers that add up to 16 is fast and easy. When 62 pops up and your numbers have dwindled, things get panicky.

There is a leaderboard. At the moment, my scores are:

Normal: 43 which places me 144 out of 9,478 players.

Advanced: 66 which places me 23rd out of 1914 players.

## Tap the 3s: Number Puzzle Game of Math by Hyemin Chung FREE

__Tap the 3s: Number Puzzle Game of Math__ comes from Hyemin Chung.

The game tests how fast you can identify multiples of 3 & 7. You are given a 3×3 grid and must tap those numbers as fast as possible. If you tap a tile that’s not a multiple, you lose points and time.

If you can complete 20 3×3 grids within the given time, (I think it’s 90 seconds), you’ll get bonus points.

This game has only 63 people on the Leaderboard. At the moment, I’m #3.

It’s free.

Test your math reflexes.
