Sue, Radisson uses tokens as "rewards" for all sorts of mental and physical "games" onboard. At the end of each cruise, they have a "token exchange."

Tokens can be exchanged for:

book marks
coffee mugs
passport holders
tote bags
jewelry boxes
napkin rings
clock
duffle bag

There might be one or more that I have forgotten. Bookmark is 1 and clock is 20, everything else falls in between.

One of Ngaire's clients has accumulated over 500 of these tokens. On our last cruise, we competed continuously whether it was trivia, pictionary, bocce in the atrium or baggo by the pool. You also earn tokens for the daily quiz.

I find the constant competition enjoyable on the cruise. I will never earn enough for the free cruise (I forget exactly how many tokens) or the Ferrari, but I still do like to keep my mind sharp.
