Games Reviewed By Jonathan Keefer
Eine and Kleine
December 31, 1998Fly with an umbrella, teleport, break your way through with a hammer to collect all the stars and get through each level.
Starries
December 31, 1998This is another one that I've played tons of times. It's like Gem Swap, but instead of swapping two pieces, you slide entire rows and columns. Very fun!
Wooden Paths 2
December 31, 1998Use transporters, magical walls and mirrors, gold blocks and dynamite to create a wooden path to cross the river.
Loop the City
December 31, 1998I love this game! I've got lot of tips for how to do it. And, once you get the hang of it, it's fun to see how fast you can solve it. It gives a different one every time too.
Parking Mania
December 31, 1998Driving is a lot of fun -- even if it's just on the computer. Driving is sometimes a lot easier than parking. Can you figure out how to parallel park?
Color Trap
December 31, 1998This one will really mess with your head! You have to click on the color that the word is telling you... but, the word says one color and IS another. Well, you'll see.
Color Balls
December 31, 1998This is a great game for focusing. Click on the balls that say the right color on them... The trick is that the words are all colored in the wrong colors!
Squares
December 31, 1998If you like Gem Swap, you should try this one. It's a lot harder, but, once you get the hang of it, it's pretty cool. Takes a first losses to get how to do it.
Gem Swap
December 31, 1998A great version of Gem Swap. It's timed, but, when you make a match, you win more time. Multiple levels.
Subtraction Blast
December 31, 1998Fire your cannons at the falling numbers. It's great arithmetic practice, and you get to shoot stuff. Can life get much better than that?
