Sci-Fi Data Card Puzzle Prop

I created this as a prop for a sci-fi TTRPG I'm running. It functions both as an immersive tabletop item and a color-matching puzzle.How to Use:Choose a correct color sequence for the data cards.Start with the holder empty and allow the players to insert the cards.After each guess, tell them how many colors are correct, but not which ones.Repeat until they deduce the correct sequence.For added difficulty, consider:Limiting the number of guesses.Adding time pressure to solve the puzzle.Assembly & Finish Notes:I used Rub 'n Buff to give the holder its color.The box was assembled with a small drop of superglue in each corner (four total).
