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
Bloons Pop 3
January 1, 1999This is like a gem swap game where you need to form rows of three of the same color, but with other cool things that happen when you line this up just right.
Bouncing Balls
January 1, 1999A fun bounce ball game where you need to make clumps of three of the same color... Before they all get too low.
Word Scramble
January 1, 1999This game does what you'd think: It gives you a row of letters and you have to rearrange them to figure out what word they make.
Orb 2
January 1, 1999This is a sequel to Orb and it's a more polished version than the first. Man, some of these levels are HARD -- and I'm proud to say that I've beat them all. Can you?
Stained Glass
December 31, 1998This is one of my all-time faves. Yeah, it's hard and takes time (past the first level), but I love figuring stuff like this out. You just have to match up all the edges.
Eight Queens
December 31, 1998This is a class logic puzzle. The goal is to place eight queens on a chess board so that no queen can attack another queen.
Magnets
December 31, 1998If you want a good challenge, this one's for you. You have to rotate pieces of this puzzle to connect like colors.
Memory 3
December 31, 1998This game take a lot of concentration. The pods open for just a second to show you what's inside... Then, you have to remember and match the color pairs up.
Venture: Capital
December 31, 1998How well do you know your US state capitals? This game gives you three ways to test yourself: choose it, spell it and locate it!
Lizard Row Slide
December 31, 1998I like this one because it's easier than those nearly impossible "slider" games. With this one, you can deal with one row at a time. I can actually solve this one!
