Yes, you can play a limited amount of games without a membership, but having a membership unlocks more games, training courses, game history, and much more.
If by this you mean, "Do Lumosity games actually keep your brain in shape?" then yes. Lumosity helps improve brain health, sharpen your memory, enhance creativity, and more. If by this you mean "Are Lumosity games fun?" then also yes. I am a Lumosity member myself, and I am addicted to these games. It tracks your high scores, and you can compare how well you did to everyone else training on Lumosity. And it is cheap, too (about $5 a month)
Lumosity is a website where you can play games that improve your brain health, memory reflexes, intelligence, and more.

Almost all games that are like Fantage will require membership of some kind, either free or paid. Without a membership, the game will not be able to 'remember' your scores, levels, etc.
Yes
There are many games like Club Penguin which you can do more with out a membership but there are none that are good with no cost.
