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
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!
Knight Switch
December 31, 1998A classic logic game. You have four knights on a small board and just have to switch the position of the two colors. Can you do it in as few moves as possible?
Whack a Difference
December 31, 1998This is like those "Whack a Mole" games, but you whack the thing that's different. Just like hitting your TV screen while watching Sesame Street!
Building Blocks
December 31, 1998This one isn't quite as easy as it looks. You just have to put the puzzle pieces together... But, sometimes, they don't end up fitting the way you think they should.
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.
Meeblings
December 31, 1998This is one of my all-time favorite games. I love these little guys and you need to figure out how to help them escape. Some levels are easy and some will take you hours.
Marble Lines
December 31, 1998I've played this game over and over and over. You shoot the ball to hit balls of the same color to make them disappear. If they get past you to the hole, you lose!
