Inspektor Nase

In the co-operative deduction game Inspektor Nase, players take turns in the role of "Inspector Nose" to try to lead everyone else to identify the correct card. The game plays over five rounds, and you start each round by laying out five image cards from the deck. If you are Inspector Nose, shuffle the number cards (1-5) and look at one of them to determine which target card players must not remove from play. You then roll five image/symbol dice, choose one of them, and place it on the clue card. The other players then debate and remove one image card from play. If they didn't remove the target card, you add one more image/symbol die to the remaining four, roll them, choose another die, and so on. If the players remove four cards and leave only the target card behind, great! If they remove the target card earlier, well, better luck next round. The team scores 1 point for each correctly removed card, with the highest possible score being 20. How well will you do?
