How do I create a symbole of victory on succeed level?

Hello,

I make a puzzle game with a 100 of level.

There are 4 differents layouts to select the level where player see small picture of the level.

Once the level is done I want to input a symbole "succed" on the miniature level.

I don't know how do that. Does some of you have advice?

When you finish a level set a value in an array from a 0 to a 1 Relate the row number to an instance variable on the level selection object, so level 1 = row 1, level 2 = row 2 or something. For each row if the value is 1 then show succeed on the level object else don't.
