On your turn, grab 1 domino from the Market, and place it in your map.

The placement rules are simple.

• It needs to connect to an existing domino and can’t overlap.
• Floors need to match. (Unless there’s a wall/door between them.)
• You can’t connect a door and a wall.

You may also destroy as much of your personal map as you want, as long as your map is connected (no loose parts) by the end of your turn. The destroyed tiles are discarded permanently. This is called Construction and can have consequences.

First, determine what floor every player is on.

• Players count how many floor icons they have.
• Then sort players based on that, low to high. (The player who has the least such icons is the first floor, the next player is the second floor, etcetera.)
• Ties are allowed: those players are simply all on the same floor. If so, they take turns in clockwise order, from start player.

Now, in that order, players attract a Tenant.

• Pick 1 Tenant from the Guests.
• You may only pick Tenants of whom you fulfill their wishes (see next section).
• Crucially, when fulfilling wishes, you also count the dominoes of other players to whom you’re “connected” as your own.
• Place the Tenant somewhere near your map.

By default, you are connected to everyone on the same floor as you. Special icons (such as the elevator) can change this.

Once done, refill the Guests and the Market, and play the next round.

From now on, it becomes important to create Rooms.

A “room” is any enclosed space (walls on all sides) with at least one door.

This expansion adds a property to some Tenants: Construction. If this icon shows (next to their star),

• You can’t attract this Tenant if you did Construction this turn.
• Additionally, they will leave if you do Construction during your turn.
• If you share a floor with multiple players, it must leave to one of them.

Guests can now have Special Wishes (that relate to Rooms). The table below explains what each icon means.

There are also some new Objects that can appear.

This expansion adds another property to some Tenants: Wallet. If this icon shows,

• They can only be attracted if they can actually pay to live with you.
• Their score = the maximum price they’re willing to pay.
• The current price of your map is the smaller of these two numbers: your LARGEST ROOM or the number of UNIQUE ICONS.

If you’re in for a challenge, also add this optional rule.

• Whenever you Attract a new Tenant, they will leave if you have the wrong price now.
• This Tenant goes to whoever has a price they can pay.
• If none exist, they are simply discarded.

At the end of the game, the final price of your map is ADDED to your total score.

Finally, this expansion also adds a few more Special Wishes and Objects. (If you choose “text on tiles”, which is the default, the way an Object works is simply written on the tile itself.)

This expansion adds some basic utilities: Power (“electricity”), Water and Wi-Fi (“internet”).

How do you get them?

• Special “generator” icons appear on the dominoes.
• If you place such a generator in your map, you get the utility if you have “Access” to it.
• You have Access if a player on the floor below you has the utility. (In a sense, the wires/pipes go up through the building.)
• If there’s no player below you—you’re the lowest floor—then you always have Access to it.

From now on, guests will wish for these things. See the added Special Wishes (and Objects) below.

This expansion adds some more Special Wishes and Objects (again).

It also adds a new property: Wandering. If a Tenant shows this icon,

• You can attract it by satisfying just one of its wishes.
• Whenever you Attract a new Tenant, however, they can leave. If another player satisfies ALL their wishes now, they go to them.

As usual, this expansion adds some special Wishes and Objects too.

This expansion makes it possible (or simply more fun and challenging) to play the game completely cooperatively.

You’ll be working together to achieve goals for your entire skyscraper, for which you’re rewarded with unique tiles and objects to place in your map. But you’ll also be threatened, such as by quality inspection, and you must collectively pass these checks.

During setup, create two decks: Goal Dominoes and Threat Dominoes. Remove any dominoes from a set that you’re not using this game.

Keep three faceup Goal Dominoes at all times, and one faceup Threat domino (drawn from these decks).

Also deal every player their own Goal Domino. It is not allowed to communicate your personal (secret) goal in any way. Your actions and choices will have to reveal it to the others.

During gameplay,

• Whenever a goal is achieved, give that domino to a player. They now place it in their map and get its reward. (This domino is considered as having “all floor types” and “no walls”, allowing you to place it anywhere.)
• Whenever a threat is not defended, place the card faceup on the table. If it has a penalty, it triggers now. If you have 3 failed threats, you lose immediately.

During the Attract Phase, check whether goals are achieved or threats not defended. Unachieved goals simply stay where they are. Defended threats are discarded and replaced by a new one from the deck.

Unless stated otherwise, goals refer to a single floor. (If it’s your secret personal goal, then it obviously refers to your personal map only.)

When the game is over, you win if all personal goals have been reached. Your score is the combined score of all the individual maps—higher is better!
