Pros: unique stacked chains, able to buy extra lives Cons: short tracks, limited powerups Why this game is currently listed with the puzzles and not the marble poppers is a mystery to me. Maybe it's because the hero of this game is a chameleon and everyone knows they have many guises. Anyway, Chameleon Gems is a near copy of Zuma in the game action, but the chain is partially stacked instead of just a long spread out single string. The "marbles" are gems in this case, and they come in three sizes. The smaller gems sit on top of larger ones with only the largest size riding along the track and available to shoot. Removing the large gem from a stack by shooting out a group of 3 like colors causes the next larger one in the stack to grow and become available to shoot at. A set number of gems must be removed to fill a progress meter. Once the meter is full no more new gems emerge and the remaining gems need to cleared before they reach the hole at the end of the track. Each level also features one or more "bonus goals" such as making a number of shots through a break in the chain or number of gem removals in a row to earn a higher rank and/or extra points. In between levels opportunities to buy additional lives and powerups are available. As in other marble poppers, powerups will also periodically appear during game play, and these are often more useful than the powerups to buy. Your character may be a chameleon, but he apparently flunked out of Color Changing 101 because he can only wear one "skin" (bonus powerup) at a time. The graphics are pretty simplistic, even for an older game. Players may also find the length of the tracks to be a bit short which can get frustrating on higher levels. It's an OK marble popper, but maybe that's why it's hiding out somewhere else.
