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
Letter Blocks
December 31, 1998This game is great for anyone who likes "search" and "word" games. Pick letters out of the grid to form words. How many can you make?
Lemonade Stand
December 31, 1998You've taken over the Coolmath lemonade stand! How much money can you make?
Math Man
December 31, 1998This is a Pac Man type game, but you have to eat the monster that solves the math equation.
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!
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.
