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
Math Lines: Xfactor
December 31, 1998This is the same as Math Lines, but you need to really know your times tables and higher multiples for this one.
Swap
December 31, 1998This game is very tricky. You have to swap the red guys over to the right while moving the blue guys over to the left. A great thinking game!
Flip It
December 31, 1998This is like the classic board game, Othello. The last one with the most of their color wins. You have to plan ahead because one move can change everything.
Pool Geometry
December 31, 1998The cool thing about this game of pool is that you get to see the geometry of the shots you're lining up! Plan your moves carefully and clear the table.
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.
Jumping Arrows
December 31, 1998This game looks like mindless fun... Then, it starts to really mess with your head! You have to pay close attention to where the arrow points, not where it's located.
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?
