number"5"actor :
“rule:"touch" "pressed"; attribute:"first blank" is "true"——change attribute "first blank num"to 5”
“rule:"touch" "pressed"; attribute:"first blank" is "false"+"second blank" is "true"——change attribute "second blank num"to 5”
“rule:"touch" "pressed"; attribute:"first blank" is "false"+"second blank" is "false"+"third blank" is "true"——change attribute "third blank num"to 5”

I think I understand what you're trying to do, but if not, please reply and clarify. You can do this with a single actor. Place the actor in all four "digit" spots on the scene. Edit the actor's prototype and add an integer attribute called self.location. Then double-click on each actor on the scene and change each actor's self.digit value to 1, then 2, then 3, then 4 in order of appearance.

In the actor's prototype rules, have a rule for inputting a digit (are you going to use the keyboard input behavior for this or your own custom buttons?). Store the value in a game-level attribute named after the location (e.g. game.location1, game.location2, etc.). So an example of this might look like:
