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
Crazy Taxi M-12
December 31, 1998This is one of our most fun games. But, you REALLY have to know your times tables to do well. Before each level, I run through my multiples in my head!
Shape Inlay
December 31, 1998This is, pretty much, like a tanagram. You've got a bunch of weird little shapes and you have to make one big, weird shape out of them. Good for people who enjoy puzzles.
MahJongg
December 31, 1998This is our newer version of this ancient board game. Find matching tiles to eliminate them. The goal is to get rid of all the tiles on the board.
Meeblings
December 31, 1998This is one of my all-time favorite games. I love these little guys and you need to figure out how to help them escape. Some levels are easy and some will take you hours.
Marble Lines
December 31, 1998I've played this game over and over and over. You shoot the ball to hit balls of the same color to make them disappear. If they get past you to the hole, you lose!
Primate Pile Up
December 31, 1998Stack the primates until they can reach the bananas... Don't let them fall!
Maze Race 2
December 31, 1998This game is similar to Maze, but you have to get to the goal before the computer does. There are cool things that you can pick up along the way to help.
Twins
December 31, 1998This is like Shisen, but easier because you are just matching balls of the same color that can be connected by no more than three lines.
Coffee Shop
December 31, 1998A great business game where you run your own coffee shop. You have to plan your budget, your recipe and how much to charge.
Water Jars
December 31, 1998This is an old standard when it comes to logic puzzles. You've got two jars and need to use them to figure out another amount of water.
