The player controls Norville "Shaggy" Rogers as well as Scooby Doo simultaneously (he automatically mimics any movements that the player makes as Shaggy) making gameplay unique. The object of the game is to find clues to solve the 4 mysteries in the game. These clues can be obtained by finding them in the open, completing a specific task, or having Scooby "sniff out" hidden clues in each area. 

These clues give the players Mystery points and more points can be earned in the bonus levels. If the player accumulates 10,000 points, they will receive an extra life. In addition, the player must avoid hazards such as small creatures, falls from high areas, or the level Monster. Each of these will add to the players "Fright Meter" which, if full, will result in the player losing a life. Once enough clues have been gathered, Velma will send you to Fred to help him build a trap to catch the monster. The player then has to lure the monster to the trap before the end of level cutscene plays. At the beginning of each level, only a small portion will be accessible, but as more clues are found, more of the level can be explored. Between each case, a game clip of the Mystery Machine driving along with on-screen dialogue from the gang inside is shown. The mysteries themselves don't have much plot before or after each case, and the person in the monster suit is usually never met until they are unmasked.

Glitch (Vampire Stage)
Show Velma all the clues you have, then run through the 'stuck' door before Velma tries to help you open it.  Then press up twice when picking something up and you will get two of that thing.
