- RANGING FROM SIMPLISTIC TO EXTREMELY CHALLENGINGThis game is challenging and there are no time limits. Many of the questions require pretty complex mental math, and sequences between numbers and letters that might frustrate some people. This is what I wanted. Most sections start off with some extremely simple questions, then they start to surprise you with harder ones. I spend some time pondering before answering some of the harder ones. There should be a better seperation between simple and difficult levels. Also, the game moves slowly between questions and does not give an IQ score. I have been using it for a week and have not seen how far the game will take me. My kids don't use it much. My personal favorite, "Brain Challenge", keeps calling me out. They grade progress by telling you what percentage of the brain you are using. If at 18%, every nook and crany of my brain is being pressure cleaned with these extremely challenging mind tortures, it makes me wonder where I'll be if I reach 70-90%. I can't say the same for "Best of Tests DS". Still, I give it 4 stars because I'm satisfied with it. I would like to see more of these brain developement games produced.
