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
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!
Phit
December 31, 1998This is one of my favorite puzzle games. They give you the pieces and you have to figure out how to slide them together so the fit into the box.
Me and the Key 3
December 31, 1998Another awesome Me and the Key game! Figure out what to go on each level to find the key. Seems like an easy one... at first!
Knight Slider
December 31, 1998Slide the pieces around the board to help the knight escape. Can you do it in the fewest moves possible?
Spectrum Genesis
December 31, 1998I love this game. It's got similar thinking as Bloxorz. You have to move the bar around to get to the star, but you have to hit all the dots first.
Color Balls
December 31, 1998This is a great game for focusing. Click on the balls that say the right color on them... The trick is that the words are all colored in the wrong colors!
Squares
December 31, 1998If you like Gem Swap, you should try this one. It's a lot harder, but, once you get the hang of it, it's pretty cool. Takes a first losses to get how to do it.
Gem Swap
December 31, 1998A great version of Gem Swap. It's timed, but, when you make a match, you win more time. Multiple levels.
