I approached this game with a little trepidation, as I'd never played the original version of it and my Tetris skills are, well, weak.
My fears were hardly justified, though. Learning how to play this is ridiculously easy - just click and rotate. However, learning how to get the maximum points and reaching the various bonus items is not so easy, as there's no nice separate list of what these items are or how to achieve them. Instead there are occasional `Tips' that show up at the top of the game - pay close attention to these, as they will greatly aid you in improving your results. Also, several of the items on the game area are mouse-over points that will bring up informative boxes that can tell you how close you are to achieving the next level and other such useful information.
Prime to my enjoyment of this game is the fact that strategic thinking pays off, not how fast you are on the trigger finger. Especially at the higher levels, you really need to think several moves ahead in order to defuse the `bombs' before they tick down to zero (but what they count is moves, not seconds), while at the same time try to keep your bonus multiplier pegged at the maximum, as every non-match move will reduce this. Figuring out how to make a specific match in the minimum number of moves is a primary skill here.
The board is composed of a grid of 8x8 jewels of five different types, and as each move rotates a group of four jewels, there are normally 49 possible moves at any point (not counting `locked' jewels that appear at higher levels and significantly reduce this number). So far, I've never seen a case where there is not at least one move out of those 49 that makes a match, though seeing that move often takes a while (there are hints that will direct you to the appropriate area if you don't do anything for thirty seconds or so). I haven't done all the math, but I suspect that this is always true, given the number of different jewels and the total number of available positions.
The graphics are quite nice, and the associated sound effects and music are decent, with a low annoyance level even when heard repeatedly. The cavernous voice announcing various things, however, is not so good, being too loud and so greatly amped by reverb echo effect as to be near non-understandable. There are additional modes of play, from Zen mode, which doesn't have any of those nasty bombs so you play at your leisure, to Challenge mode, which sets very specific goals, such as figuring out how to eliminate every jewel on the board in a single move (that one took me a couple of hours to do). But the best play is the Classic mode, as it calls on all your skills and thinking to really progress up the High Scores table.
Better than the original (I draw on my wife's evaluation here, as she has played that version), but perhaps a little too much of the finer points are hidden and not so easy to discover. Still, an engrossing strategy game that will make you think a bit.
