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
Loan Consolidation
December 31, 1998This game is like Bricks Breaking, but you have to match up the debt block with money blocks of the same color. Be sure to avoid the credit cards blocks!
Sliding Blocks Flash
December 31, 1998This game is like Rush. You have to slide a bunch of blocks around to get the one block out. Lots of great thinking on this one.
Kakuro
December 31, 1998I thought this was impossibly hard at first. The key is to fill in all single squares first, then look for doubles and up. Cool that you can ask for hints!
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.
Monkey Banana
December 31, 1998You have to find the path for the monkey to get the banana. Mmm bananas. The trick is that the monkey takes a turn every time he can, so you have to plan ahead.
Four Piece Tanagram
December 31, 1998A classic puzzle game where you have a set of weird shapes and you have to put them together to form a given, bigger weird shape.
Penguin
December 31, 1998Another great logic game. This one is similar to Bridge Crossing and Wolf, Sheep and Cabbage, but this time, you have to get the penguins to the opposite shore.
