opolyx is a free, online Monopoly-style board game you play in the browser. This page is a quick, plain-English explainer of the classic rules opolyx uses — enough to sit down and play right away. When you want the fine print, the complete rulebook and a turn-by-turn walkthrough are one click away.

How do you play Monopoly?

A turn is a short, repeatable loop. On opolyx most of it is automatic — you just make the decisions — but the underlying rules are the ones you already know.

1. 1
   Roll the dice and move

   Roll the two dice and move your token that many squares around the board, clockwise from where you are.

2. 2
   Buy it or send it to auction

   Land on an unowned property and you may buy it at its list price. Decline, and it goes to auction for every player to bid on.

3. 3
   Pay rent if it is owned

   Land on a property someone else owns and you pay them rent. Rent is higher on full colour sets and rises with each house you build.

4. 4
   Collect salary at Start

   Every time you pass or land on Start you collect your salary, which keeps cash flowing into the game.

5. 5
   Build, mortgage, and trade

   Own a full colour set to build houses for higher rent. Mortgage properties to raise cash in a pinch, and trade with rivals to complete sets.

6. 6
   Doubles roll again

   Roll doubles and you take another turn — but roll three doubles in a row and you go straight to jail.

How do you win at Monopoly?

You win by being the last player standing — everyone else goes bankrupt. That outcome almost always comes down to a few practical habits rather than luck:

• Complete colour sets. A single street earns little; a full set lets you build, and houses are where the big rent comes from.
• Trade to finish sets. The fastest route to a monopoly is usually a deal, not the dice — offer cash or a spare property to get the square you need.
• Keep a cash cushion. Building is good, but going broke when you land on a rival’s hotel ends your game. Leave enough to survive the next few rents.
• Mortgage deliberately. Raising cash on a quiet property to build on a busy one can be the right call; just remember the unmortgage cost later.
• In Speed, use the third die. The Speed die can carry you onto the property you want or hand you a free move — plan around it.

How does the auction rule work?

The auction is the most-skipped real rule in tabletop Monopoly, and it changes the game. When a player lands on an unowned property and chooses not to buy it, the property does not stay on the shelf — it is auctioned to all players. On opolyx the auction is turn-based: each player gets a short window (about ten seconds) to raise the bid or pass, and the highest bidder wins it, often well below or above the list price depending on who wants it.

What are the jail rules?

You go to jail by landing on the Go to Jail square, drawing a card that sends you there, or rolling three doubles in a row. While in jail you still own everything and still collect rent. To get out you can roll doubles on your turn, pay the fine, or simply wait out your turns — after which you leave and move with your roll.

What are the Speed die rules?

Speed mode adds a third die — the Speed die — on top of the usual two, and it is what makes a game move fast. It can show a number, a Bus, or an X:

• A number face adds straight to your move, so you cover more ground each turn.
• A Bus face lets you choose your move instead of being stuck with the dice total.
• An X face sends you to the nearest property — handy for landing on the square you have been eyeing.
• A triple lets you teleport anywhere on the board and roll again.

How long does a game take, and how do you make it faster?

A classic Monopoly-style game can run long — once players are circling the board collecting rent, it can stretch for an hour or more. If you want a quicker game, opolyx gives you three reliable levers: pick Speed mode (the third die and faster turns shorten everything), play with fewer players, and fill empty seats with bots so nobody is waiting on a slow human. Combine all three and a game can be over in a fraction of the time.

How many dice are in Monopoly?

Classic Monopoly-style play uses two dice — you roll both and move the combined total, and matching numbers (doubles) let you roll again. Speed mode adds a third die, the Speed die, for a total of three. The two standard dice still set your basic move; the Speed die layers its number, Bus, or X effect on top.
