Star Trek Puzzle
This is a virtual version of a Star Trek jigsaw puzzle, available for free on the website "All Top Games." There are 26 puzzle pieces that you have to play around with to fit into their appropriate places. The puzzle is a little tricky, so take your time on it, particularly since there are no time constraints. If you put any piece in the wrong place, you can change its position by dragging it out of the box using the mouse.
Star Trek Memory
You can play the game online on the website "All Top Games." When the game begins, click "New Game." You will then be presented with 42 cards turned around. You have to turn each card and randomly pick out another card to match it with the first one. If it doesn't match with the first card, both the cards will turn back automatically, and you can turn around another card to make a pair. You get a limited time span to complete the game, so make it quick and try to get as many card pairs as you can.
