Minesweeper, by Michael Lee
Originality - A minesweeper clone, but with many features not present in most ticalc.org clones at once
Gameplay/Controls - Fast, except scrolling and menu selection is a bit hard due to the way key delay is handled. Nice controls and easy to use game.
Graphics - Beautiful 3 level grayscale graphics. The grayscale vanishes completly during scrolling, though, and in this contest-submitted version, there are some display glitches. Menus are well layed-out.
Entertainment factor - Great replay value and should entertain any puzzle/minesweeper fan.
Useability - If there are bugs, they did not seem to hinder gameplay except once, where I had all flags but game would not end. I did not get constant crashes. It would be nice if cancelling in the option menu did not exit the entire game, though, but instead, returned to the main menu.

Splut, by Ikkerens
Originality - This would have gotten a very huge 20/20 because the game by itself is very original and I never saw anything like that for the calculator before, but since it is a team project (the levels were done by someone else), there is a penalty of 5 points on originality.
Gameplay/Controls - Key detection is way too fast, making it nearly impossible to choose stuff in the menus and inside the game, it makes it extremly hard to control your character. The control choice is fine, though.
Graphics - Awesome, perfect graphics in-game and nice menu layout. This gets a perfect score.
Entertainment factor - If this wasn't for the key detection being too sensitive, making the player give up faster, this would get max score. The difficulty for levels besides that is very good and there are levels that are easy enough for beginners and hard enough for experts, with multiple difficulty settings.
Useability - Took a while to get used to and I had some crashes on exiting in the contest-submitted version, from time to time. Besides that and the key detection issues, the game should be easy to use.

Jump, by Ztrumpet
Originality - An interesting platformer concept. Simple but pretty efficient.
Gameplay/Controls - Not too bad, except that there seems to be collision detection issues when falling on the edge of the next platform (you fall through the floor). Also, having to press 2nd to see the score and being forced to input a name is pretty annoying when you want to replay immediately afterward. At first, when I died, I thought my calc froze. Other than that, controls are pretty good and simple.
Graphics - Simple but nice at the same time. Smooth framerate and nice block jumping animation
Entertainment factor - Extremly addicting. It would be even more if going through the score/game over screens was not this long.
Useability - It only loses one point due to the score/game over screen issue and the collision detection problem, but it is not enough to hinder gameplay that much.

Blur, by FinaleTI
Originality - Tunnel game clone, although there's an easter egg and unlike most other tunnel games, this one scrolls left instead of up/down.
Gameplay/Controls - Not too bad, although a bit hard and if you trigger the easter egg, it is barely even playable.
Graphics - Kinda simple, although they do the job well.
Entertainment factor - Some easier difficulty modes and/or increasing difficulty, starting from something a bit easier (larger road) would be nice. Kinda entertaining/addicting for a while, though.
useability - No bugs and errors. It may just need some difficulty adjusting.

Wacky fun Random Numbar Generator, by Snake X v1.0000069
Originality - Number guessing game.
Gameplay/Controls - Quite slow-paced but controls are OK otherwise.
Graphics - None
Entertainment factor - It can be addicting for a while, especially for people who expect to see Nick Disabato password for real, but it gets boring after a while since it's just a guessing game.
Useability - If someone ports WFRNG to another calc or language, it would at least be nice if it did not have bugs... WAIT! Bugs in a GUESSING GAME?? Ok. Well it's still a classic I guess :-P. The Game.
