Bejeweled Twist for Nintendo DS
The matching game with a literal twist - Bejeweled Twist, where you will rotate four jewels at the same time. Even without a match you can proceed with the game, unlike earlier incarnations when the gems would revert back to their original positions. There are also new gems like the bomb which opens up mini games which get tougher as you miss matching more bombs. Then there is the flame and lightning jewels that need quartet or pentad of same gems to clean up rows or columns.
Also play doom gems that fill up spaces and cannot be matched. Fruit gems takes out all similar coloured gems also gaining time on bomb gems. Try the calm Zen mode sans timers and chimes. Or if you are one for fast paced action then Blitz a five minute game within which you must match as many gems as possible.
The preserver challenge lets you retain 30 yellow gems at all times. Spectrum challenge is where a particular colour is chosen to be matched again and again.
