Favorite Coolmath Games: Clicker Heroes, Block the Pig, Tube Master
Jon is a strategy game fanatic - his favorite games are open-ended puzzles with strategic, complex systems and creative solutions. He loves that games allow anyone to share in unique experiences, like designing a subway system in Mini Metro: London or building a civilization in Pre-Civilization Bronze Age. He has been helping discover and design games that make you think for Coolmath since 2014.
In his free time, Jon enjoys biking, playing board games, card games, Nintendo, Xbox and PC games. In past lives he has helped design board games and card games, including the Chaotic Trading Card Game and the Twilight movie (yes, that Twilight) board game series.
Jon is a graduate of NYU’s Stern School of Business and is deeply passionate about using games as a way to help people think, learn, and grow. His accomplishments in the web gaming space have given him opportunities to share his insights as a speaker and panelist at industry events such as GDC, Gamescom and Pocket Gamer Connects.
Games Reviewed By Jonathan Keefer
Field Separation
December 31, 1998I thought this one was boring - until I figured it out. Now, I think it's great. The trick is that the fields must be big squares or rectangles. Find a good place to start.
Civiballs
December 31, 1998When you cut the chain, how will the ball swing? Get the colored balls into their matching buckets... But, you'll need to do some planning!
Castle Defense
December 31, 1998You must defend the castle by shooting the oncoming enemy before they reach the end of the road. You earn money to buy more weapons.
Fractone
December 31, 1998Click on the fraction squares to make pairs that have a sum of 1... and do it as fast as you can!
Rotate and Roll Player's Pack
December 31, 1998You are going to love this one! When I found it, I played it for a solid week until my eyes were blurry. Just tip the game to help the little ball guys escape.
Number Twins
December 31, 1998This is like our game, Twins, but we put numbers on the balls. You have to match up numbers (like in our game Shisen) to make the correct sums.
Rotate and Roll
December 31, 1998You're going to love this one! When I found it, I played it for a week until my eyes were blurry. Very simple - just tip the game to help the little guys escape.
Crazy Taxi M-12
December 31, 1998This is one of our most fun games. But, you REALLY have to know your times tables to do well. Before each level, I run through my multiples in my head!
Shape Inlay
December 31, 1998This is, pretty much, like a tanagram. You've got a bunch of weird little shapes and you have to make one big, weird shape out of them. Good for people who enjoy puzzles.
MahJongg
December 31, 1998This is our newer version of this ancient board game. Find matching tiles to eliminate them. The goal is to get rid of all the tiles on the board.
