Christmas comes however annually – as do Christmas occasion video games. With such little apply it’s onerous to get good at any of them.
Let me assist. I’m going to share with you some professional suggestions, examined by mathematical modelling, on win one of the vital standard video games: Dangerous Santa – also referred to as Soiled Santa, White Elephant, Seize Bag, Yankee Swap, Thieving Secret Santa, or just “that present-stealing sport”.
This isn’t recommendation on being a foul sport. It’s about being a very good Dangerous Santa – which is the secret. You would possibly even come away with a very good reward and bragging rights.
How Dangerous Santa works
Dangerous Santa is a variation of the basic Kris Kringle (or Secret Santa) sport, by which every visitor receives an nameless reward purchased by one other visitor. A part of the enjoyable (for others) is the unwrapping of foolish and ineffective presents, which is completed one after the other.
Dangerous Santa spices issues up. All of the presents are pooled. Friends take turns to decide on one to unwrap. Or they’ll select to “steal” a present already opened by another person. The individual shedding their reward then will get the identical selection: open a wrapped current or steal another person’s.
It’s a very good various to purchasing a present for everybody, and a good way to break friendships.
The order of gamers is normally decided by drawing numbers from a hat. That is necessary, since you’ve in all probability already famous the drawback of going first and the good thing about going final. The best guidelines can mitigate this. There are not less than a dozen totally different variations of this sport printed on-line, and a few are a lot much less truthful than others.
How I examined Dangerous Santa
One of the simplest ways to check Dangerous Santa rule variations and enjoying methods can be to watch video games in actual life – say, by attending 1,000 Christmas events (funding our bodies please name me).
I did the subsequent smartest thing, deploying the identical kind of pc modelling (often known as agent-based modelling) used to know every part from bidding in electrical energy markets to how the human immune system works.
In my mannequin there are 16 digital company and 16 presents. Every has totally different current preferences, score opened presents on a scale of 1 to 10. They’ll steal a present they fee higher than a 5. To make it fascinating, three presents are rated extremely by everybody and there are three nobody actually needs – in all probability a novelty mug or one thing.
Or one thing.

After simulating 50,000 video games with totally different guidelines, I’ve discovered a algorithm that appears essentially the most truthful, it doesn’t matter what quantity you draw from the hat.
Selecting the fairest guidelines
The next graph reveals the outcomes for 4 totally different sport variations.
The upper the road, the better the general satisfaction. The flatter the traces, the fairer the end result. (If presents have been chosen randomly with no stealing, each participant’s common satisfaction rating can be 5.)
Probably the most unfair end result comes from the “darkish blue guidelines”, which stipulate that any reward can solely be stolen as soon as in any spherical. This imply should you’re the final individual, you’ve bought the most important selection and get to maintain what you steal. If you happen to go first, you’re certain to lose out.
Fairest and finest Dangerous Santa guidelines
Probably the most truthful outcomes come from the “purple guidelines”:
A present will be stolen a number of occasions every flip. This retains presents shifting between company, which provides to the enjoyable.
As soon as an individual holds the identical reward 3 times it turns into “locked”, and might not be stolen. This evens the sport out so much. Later gamers nonetheless see extra presents, however earlier gamers have extra probability to lock the reward they need. It additionally ensures video games don’t go on for hours.
After the final participant’s flip, there’s another spherical of stealing, beginning with the very first participant. This additionally provides them an opportunity to steal not less than as soon as – and a slight benefit. However total, these guidelines present essentially the most even outcomes.
Like most video games, the foundations are’t good. However the maths reveals they’re higher than the alternate options. If you wish to check different situations utilizing my mannequin, you possibly can obtain my supply code right here.

Three recommendations on sport technique
The best guidelines assist degree the enjoying subject. They don’t get rid of the necessity for strategic pondering to maximise your probability to get a present you need.
As in actual life, seemingly truthful guidelines will be manipulated.
One factor you can do is crew up with different gamers to govern the “three holds and locked” rule. To do that, you’ll want not less than two co-conspirators.
Say your pals Donner and Blitzen have their most popular presents, and now it’s your flip. You steal Blitzen’s reward. Blitzen in flip steals Donner’s, who steals yours, and so forth. Donner and Blitzen find yourself holding their chosen presents a second time, then a 3rd. You helped them out, after which can select one other reward.
Alright, let’s go over the plan once more. I steal this reward, then you definately steal that reward, and then you definately steal my reward.

In aggressive markets one of these co-operation is normally know as collusion – and it’s unlawful. In sport, it could merely be referred to as dishonest. So I’m not saying it is best to do that; I’m merely explaining how the technique works. If you happen to do that and find yourself on the naughty record, don’t blame me.
I haven’t but examined guidelines variations in my mannequin to see how this collusion can finest be eradicated or minimised. Possibly by subsequent Christmas. (Or perhaps not – for me, dishonest by maths is half the enjoyable of the sport.)
So let me go away you with two completely official methods.
First, and most clearly, you will need to steal presents!
My modelling quantifies how essential that is. I simulated a sport by which 4 company won’t ever steal a present. These company are 75% much less happy with their remaining presents than the gamers who do steal. They’re additionally a lot much less enjoyable at events.
Second, steal even when there’s nothing you need but.
Steal the current you assume another person will need. If a later participant steals your reward, you get one other probability to choose once more when extra presents have been opened.
And if somebody will get Grinchy if you use these strategies to bag one of the best reward, simply you’ll want to inform them you examine it on The Dialog.
