Game is functional, and while I would be at first concerned that there was no case or container for it, the toughness of the bubble container it came in settled the worries. Cartridge may have trouble reading if it's been a long while since it was played, but simply remove and re-insert to fix that.im a big chaotic fan, and this is the only chaotic game so i have to like it. its a little hard to get used to at first but then its easy and its nice to have multiplayer mode with a friend that has the game as well. and i mean its so cheap for a ds gamei like it so far you have use pen the whole time though but it still pretty fun i would give it to my kid if have oneI enjoyed this game on wii,so had to have it for my DS. I'm not one least bit, disappointed. This game challenges the strategic part of the mind,also the memory. I hope you like it as much as i do.My son like it. He can't seem to stop playing unless I tell him to stop and do other things. :)) Which really bother me.Inexpensive and entertaining Grandson played all school break. Game was easy to play, arrived in excellent shape and worked well.purchased for my 10 year old boy, he loves games like this, him and his friend play it all the timeI bought this for my nephew for christmas - 13 years old - and he really likes it. He hadn't heard of it before I gave it to him but once he started playing, he said that it was a really good choice. So glad as I am never sure of these things!!
