A MortalCase game runs 2.5–3 hours and gives every person in the room the same job for the whole of it, which is rarer at a family gathering than it sounds. The work is all in what you do beforehand: which game you buy, who you cast as the 8 Primary Characters, and what you say in the first 5 minutes. Get those right and the shy 14-year-old and the uncle who talks over everybody both have a good night.

A MortalCase murder mystery is the best thing you can put in the middle of New Year’s Eve, because it gives the long sag between dinner and the countdown an actual shape. The whole trick is timing: open the game around 20:30, work backward from midnight rather than forward from arrival, and leave 30 minutes after the Reveal for everyone to argue about who they suspected. Then let the countdown be the second finale.

Christmas is the hardest night of the year to plan an activity for, because you don't choose the guest list and you can't predict the mood. This guide walks you through what matters most when you run a MortalCase murder mystery on the day: reading the room before you pick a game, keeping the meal from pinning everyone to a chair, lighting the evening with what's already on your walls, and working backward from the hour people need to leave.

Halloween is easy to overdecorate and hard to give a shape to. This guide takes you from the invitation to the last hour: what to ask guests to wear so nobody arrives feeling wrong, how to lay out a room so 20 people aren't queueing at one table, what food survives a mask, and how to let a MortalCase mystery carry the conversation while you keep an eye on the clock. Most of it is lighting and nerve.

Nobody at a MortalCase murder mystery is being judged on their outfit, and 1 clear item is enough. Your Character Guide already points at most of the answer: a hat, gloves, a badge, a jacket that suggests money you can't explain. Guests who want to go further will, without being asked. The point of dressing up is to help you believe the room, not to win it.

A MortalCase Halloween party gives your guests something to do after the costume compliments run out, which is the hour most Halloween parties lose. Pick 1 idea inside Halloween instead of all of them, let low lighting do the decorating, keep the food one-handed, and let the game structure carry the evening. Halloween also draws the biggest guest list of the year, so decide how many characters you want in the room before you invite.

An 80s arcade murder mystery is one of the easiest themes to get right and one of the easiest to overbuild. The neon, the cabinets, and the soundtrack matter far less than a room your guests can move around in. Light it in 1 color, build 3 places worth walking to, ask for 1 costume detail rather than a full outfit, and let the MortalCase Character Guides do the work of starting conversations.

Decorating for a MortalCase murder mystery is mostly a lighting job, and lighting is the cheapest transformation there is. Turn the overheads off, pick 1 visual language and repeat it, and build 3 zones worth walking between rather than dressing every room. Keep the food, the drinks and the evidence away from each other. Anything that makes it harder for guests to move or talk is decoration working against you.

Your guests can eat, drink, and keep questioning each other at the same time, as long as the menu is built for a party that moves. Build the menu around one-hand foods, self-service drinks, and natural breaks so guests can keep mingling, comparing evidence, and playing their characters. You'll also find where to put the buffet so it does not sit on top of the evidence, how to theme a few details without cooking all day, and what to do about food safety across a 3-hour party.

Hosting a MortalCase party outdoors takes more planning than hosting inside, and most of it is unglamorous. This guide covers the parts that decide whether the evening holds together: where the group can stand and still hear each other, how printed material survives an evening outside, what to light and in what order, and the point at which you call it and move everyone in. Work through it once and the night stops depending on the forecast.
