Trying to remember the names of two kids shows from the 90's. The first had 3 kids jumping out of a black van and going into a tower block where they entered a lift. In the lift was a screen and a talking head. One if the games they had to play was called "alphabet soup". The second i think it was set in space, kind of like a kids version of crystal maze. At the end they had to run to the spaceship before the time ran out or they were left on this make believe planet. Anyone remember them?
