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
Sudoku
December 31, 1998The highly addicting number puzzle. Three difficulty levels to choose from, unlimited boards to solve!
Parking Mania: Zoo Escape
December 31, 1998We got a LOT of requests for this game! The driving is easier than our "extreme" versions and you get to rescue animals. What could be better?
Seesaw Logic
December 31, 1998I really like this one. It seems really easy at first, then you really have to think. You are shown a bunch of objects on scales and have to figure out which one is heaviest.
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?
Pool Geometry 2
December 31, 1998This is just like Pool Geometry, but it's not your standard, rectangular table. These new angles change how everything works!
Galaxo Chimp
December 31, 1998Help the chimp astronaut collect all the stars. You'll have to plan ahead and figure out some weird angles!
