WARNING: SERIOUS SPOILERS TO FOLLOW! DO NOT READ BEYOND IF YOU WISH TO DISCOVER ALL THE GAME ON YOUR OWN!
The game comes with a blindfold, but it's not quite high quality (we much prefer the LH padded one for example). There's also a "piece of cloth for tying" - this is satin like and not very comfy either. We have our bed equipped with under the bed restraints and use our own cuffs and stuff if needed. You can play the game once or twice around the board, but we usually just do once, as it takes at least a couple of hours anyway. You will need a stopwatch of some sort as some tasks require a time limit (this can vary broadly from seconds to several minutes) but any phone has an app to handle this so you should be set. The instructions also say you'll need massage oils/candles. Other toys might turn useful too (eg. for mastrubation). Internet and a device for video playing (a smartphone will do) is handy. You could also need one (small) coin. Have some ice cubes ready, and maybe some fruit and chocolate. Dressing gown cord, wooden spoon, belt, nipple clamps - some other items that might make an appearance.
Here are some sample stuff from the cards to give you an idea of what you'll be needing:
"Send your sub to the kitchen to select three different snacks for you to enjoy...." (I will not spoil every surprise for you though!) :)
"Gather together a selection of impact play toys / items from around the house..."
"...Choose 5 different items to spank them with. After each swat ask them to guess what the item is..." (different card from the previous one and not all tasks cited)
"The Dom(me) can collect a number of sex toys, kitchen implements, hairbrushes, ropes, scarves, pegs from around the house in preparation for use on their sub. They should collect at least 10 different things and lay them out in the bedroom..." (it continues but I'll leave some surprise in it!).
"You can choose the outfit your sub wears for the next two turns."
"Send your sub into another room with instructions to text you 3 intimate images of themselves..."
Some of the cards are about roleplay. Sometimes just a scene as a task, but some are in the final "reward" cards so these could be full plays. Such is: doctor, shoplifting, schoolgirl/boy (ruler!), stranger in a bar, cop/driver, hitchhiker, secretary...
Clothes are actually important in this game for several tasks. So maybe a full (elegant/sensual) clothing would be suitable. (Again, we have successfully played the game starting out with only our sexy underwear once, so it's not a biggie, you just need to improvise.) You might get asked to take off a specific number of items and have some left, or undress completely only to put some items back on...
"Present your Dom(me) with a choice of 3 sets of underwear for you to wear..."
Well, I do hope it is not more information than what you would have wanted mysteron, and I didn't ruin all suprises. I also kind of feel like a bitch for helping you gain advantage in the game with your wife... Have fun.
We are now in the stage of incorporating other cards (from other games) to diversify the tasks in this board game. :)
