The classic property-trading board game, reimagined for the web. Match up with friends or bots, in Classic or fast Speed mode — nothing to download.

Same buy-build-trade-bankrupt heart of the classic property game, rebuilt to play instantly online.
Modes, mini-games and collectibles the cardboard box never had.
Play the full classic game, or switch to Speed — a third die, faster rents and uneven building for quick matches.
Land on the Jackpot square, pick your numbers and roll for a payout — a fair, bank-funded twist on the board.
Fill the table with friends, fill empty seats with bots — your call.
Win matches to earn field cards across four rarities — a small rent boost, mostly bragging rights.
Every roll and payment is server-checked — no miscounts, no cheating.
It's the property-trading genre nearly everyone grew up with: you circle a board, buy the squares you land on, charge rent when rivals visit, and slowly squeeze everyone else off the table. The last player with money standing wins.
opolyx takes that timeless loop — roll, buy, build, trade, bankrupt — and rebuilds it for the modern web. There's no box to dig out of the closet, no setup, no arguments over who's the banker, and no half-finished game abandoned on the dining table. You open a browser tab and you're playing in seconds, against friends across the world or against bots at any hour.
A physical set is wonderful — until someone knocks the board, the bank runs out of notes, or three players quietly give up two hours in. Online, the banker is automatic and always exact, rent is collected the instant a token lands, auctions and trades follow the rules every time, and a game that would sprawl across an evening can be wrapped up in minutes with Speed mode. You can also play with people who aren't in the room — which, most of the time, is everyone.
We didn't just photocopy the cardboard. opolyx adds two distinct game modes, a Jackpot dice mini-game, tables of up to six, and collectible cards you earn by winning — touches the original genre never had. Underneath, every dice roll and payment is verified on our servers, so a match is always fair and impossible to fudge. It's familiar enough to pick up in one turn, and fresh enough to keep you coming back.
A faithful full-length game, or a fast-paced sprint — pick the pace that fits your table.
The complete property-trading experience, true to the tabletop original — for when you want the long, scheming, table-talk kind of game.
Everything compressed. A third die, sharper rents and looser building rules turn a marathon into a quick, brutal sprint.
Start a table and share the link, or jump into an open game. No download — it runs in your browser.
Move around the board, snap up properties, build, and strike deals in built-in auctions and trades.
Charge rent, dodge bankruptcy and squeeze your rivals until you're the last player standing.
The board rewards patience, leverage and a little ruthlessness. Here's where new players gain the most.
The squares just past Jail get landed on constantly. A complete mid-board set with houses out-earns the flashy expensive corner most games.
The rent jump from two houses to three is the steepest on the board. Get there before your rivals and rent does the bankrupting for you.
When a player declines a property it goes to auction. Snapping up bargains — or blocking an opponent's set — quietly wins games.
Don't sink every coin into building. A bad run of rent payments with no cash on hand is the fastest way to a forced bankruptcy.
One missing property can be worth far more than its price. Overpay in a trade if it hands you a full colour group and the rent multiplier.
With uneven building and a ticking mortgage clock, hesitation loses. Pick a set, pour in, and pressure rivals before the dice catch you out.
From quick solo matches against bots to six-player grudge nights — here’s what people say.
Finally a property game my whole group can play from different cities. Speed mode means we actually finish — no more games abandoned at midnight.
The automatic banker alone is worth it. No miscounts, no arguments about rent — you just roll and play. The Jackpot square is a fun little gamble too.
I jump in against bots on my commute and play friends at night. Loads instantly, runs great on my phone, and the collectible cards keep me grinding wins.
