Rating: (1-5)

Relevance to objectives: 5 - The game provides five colors and five shapes to choose from to put on the mudball and the target wall has the pattern generated at random which, through logical selection, the student can copy and elevate the zoombini.
Provides practice of relevant skills: 2 - Some of the logical reasoning power come basically through trial and error.  This may vary depending on individual's personality.
Likely to arouse/maintain interest: 4 - The game set up is a challenge initially and will keep the student's interest provided the student can relate to the logical patterns and does not get frustrated.  Once the initial two or three puzzles are solved, the interest is greatly reduced.
Likely to be comprehended clearly: 3 - For the most part, the directions are fairly straight forward in that the player strikes the target to hit the wall.  The "buttons" the player must click on in order to play are not so clearly highlighted when first beginning, but once found are easy enough to understand and utilize.
Technical quality (durable, attractive): 4 - As shareware download, the product is as good and durable as the user's equipment.  The graphics are clear, colorful, and would keep the attention of younger children.
Game: Winning dependent on player actions (rather than chance):  5 - Yes.  If the player does not pick the correct colors and shapes to fit the pattern, the player will not win.
Simulation: Validity of game model (realistic, accurate depiction):  2 - I can not say the game is "realistic" as it uses colored mudballs thrown against a block wall to focus the problem-solving skills of the player. It is valid in using problem-solving skills to determine patterns, however the setting is not a realistic one.
Evidence of effectiveness (e.g. field-test results): 4 - I would have to say, that even without the realism, the game is effective.  The full game version is rated for grades 3 to 7.  Two of my sons, grades 7 and 10, have yet to get tired of playing it after a two week period.
Clear directions for play: 3 - The directions are simple and straight-forward, although some players might not understand them due to the poem-like way they are conveyed.  Even so, trail and error will quickly make the goal clear.
Effectiveness of debriefing:  5 - The little zoombini either reaches the top of the wall after the player has completed the pattern or it doesn't. The player moves to the next level or not.  The activity and sounds of the zoombini let the player know if the goal has been achieved.
