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
Snorzees
December 31, 1998Tip the game field to move the Snorzees around. Your goal is to delete group of Snorzees of the same color. Beware of glass and rocks!
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!
Piles of Balls
December 31, 1998Clumps of balls drop down from the top and you have to rotate them so that they form groups of three or more of the same color. Can you keep up with this one?
Rubik's Cube
December 31, 1998This is a computer version of a Rubik's Cube. You can twist it all around to check for your next moves.
Wolf, Sheep and Cabbage
December 31, 1998This one's another classic. You have to get a wolf, a sheep and a head of cabbage across the river... so that nothing (or no one) gets eaten in the process.
Extreme Parking Mania
December 31, 1998One of our most popular games ever. Hard driving and lots of obstacles to figure out... Then, you have to park!
Find the Pair
December 31, 1998How fast can you find the two things that are the same size, shape and color?
