Square One City is a persistent, multiplayer 3D city built on a single shared board. Every square is a real spot in the skyline — buildings rise as players claim them, and every placement is visible to everyone who visits.
Roll, move, and claim squares to put your own buildings, signs, and storefronts on the board.
Buildings, billboards, and Forever Squares carry real advertising — yours to display for as long as you hold the square.
No separate matches or resets. It's the same city, the same board, and the same players building it together.
Bricks, the in-game currency used to build and buy placements, are a limited license to use inside the game — not money, not a security, and not a wager. Square One City is a city-building game, not gambling. Full details in the Terms of Service below.
Google or email sign-in — no separate password to make.
Move around the board and put a building on an open square.
Top up with real money whenever you want to build bigger, faster.
Hold placements, take over open squares, and grow your corner of the city.
Bricks are the in-game currency you spend to build, buy placements, and take over squares. Purchased with a card, processed securely by Stripe.
All prices in USD. Bricks have no cash value and can't be redeemed, exchanged, or sold — see the Terms of Service below. All sales are final.
Square One City was founded in September 2026 in Port Charlotte, Florida by William Andress. It's a bootstrapped, three-person digital agency that builds and operates its own 3D advertising platform: a persistent, player-built city where brands own real placements — billboards, storefronts, whole-building screens, and Forever Squares — seen by everyone who visits. The platform, the placement marketplace, and the payments backend are designed, built, and run in-house, with Claude — Anthropic's AI — as the engineering partner across the whole stack, from the three.js city to the Cloudflare and Stripe backend.

Effective date: September 14, 2026. Operator: Square One City, an independent studio founded by William Andress and operated from Port Charlotte, Florida, USA ("Company," "we," "us," "our"). Contact: support@squareone.city.
By creating an account, accessing, or using Square One City (the "Service," "Game," or "Platform"), you agree to be bound by these Terms of Service ("Terms"). If you do not agree, do not use the Service. We may update these Terms at any time as described in Section 18; continued use after an update constitutes acceptance.
You must be at least 18 years old, or the age of majority in your jurisdiction, to create an account, make a purchase, or use the Service. By using the Service, you represent that you meet this requirement. Accounts found to belong to a person under this age will be terminated, and Section 9 (Account Suspension & Termination) governs — including forfeiture of all credits and purchases.
You must register using Google, Apple, or email sign-in and maintain accurate account information. One account per person. You are responsible for all activity on your account and for keeping your login credentials secure. Accounts are personal and non-transferable — you may not sell, trade, gift, or share your account or login credentials.
"Credits" are a limited, non-transferable, revocable license to access features within the Service — they are not currency, property, or a financial instrument.
Purchases such as Forever Squares, building facades, and sign-spinner or other ad-space rentals grant you a revocable, non-exclusive license to display content in that placement subject to these Terms — they do not convey real property, real-world ownership, equity, or any transferable asset outside the Game.
All payments are processed by Stripe. We do not see or store your full card number. Prices are displayed before checkout.
ALL SALES ARE FINAL. Once a purchase is completed, you have 24 hours from the time of purchase to contact us at the email above if something is genuinely broken (e.g., you were charged but received nothing). Reviewing and resolving such reports within that window is entirely at our discretion — we are not obligated to grant any refund or credit even within the 24-hour window.
After 24 hours, you are entitled to nothing further — no refund, no credit reversal, no compensation of any kind, for any reason, including but not limited to: change of mind, dissatisfaction, account suspension or termination (Section 9), removal or modification of a placement (Section 5), or discontinuation of the Service. Purchased Credits and placements carry no guaranteed future value or availability.
This policy does not limit any right you separately have with your card issuer or bank to dispute a charge. However, filing a chargeback or payment dispute for a purchase that was correctly delivered is a violation of these Terms and grounds for immediate account termination and forfeiture under Section 9, and we reserve the right to contest disputes with the evidence available to us.
Content you place on building facades, signs, or other placements must comply with our content guidelines and all applicable advertising laws and third-party platform policies (including any platform used to advertise the Game itself). Prohibited content includes but is not limited to: illegal content, fraud or scams, deceptive claims, gambling or real-money wagering offers, adult content, hate speech, harassment, malware or phishing links, and infringement of others' intellectual property. We may reject, remove, or replace any content at our discretion without notice and without refund.
We reserve the right to refuse registration, access, or service to anyone, at any time, for any reason or no reason, at our sole discretion, including before an account is ever created.
We may suspend, restrict, or permanently terminate your account at any time, for any reason or no reason, with or without prior notice, at our sole discretion. This includes, without limitation, suspected violations of these Terms, suspected fraud or chargeback abuse, suspected multi-accounting, disruptive or abusive behavior, or simply our own business judgment.
Upon suspension or termination for any reason: all Credits, placements, and account data are immediately and permanently forfeited with no refund, credit, or compensation of any kind. You have no ownership interest, vested right, or entitlement to anything in the Service that survives termination of your account.
You agree not to: cheat, exploit bugs, or manipulate game mechanics; use bots, scripts, or automation; harass or threaten other users; impersonate any person or entity; upload content that violates Section 7; attempt to reverse-engineer, scrape, or interfere with the Service; create multiple accounts to evade a suspension; or use the Service for any illegal purpose, including gambling or money laundering.
All Square One City software, design, trademarks, and content (excluding user-submitted advertising content) are owned by the Company. You receive no license to use them outside the Service except as expressly permitted.
THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, OR THAT ANY CREDITS, PLACEMENTS, OR ACCOUNT DATA WILL BE PRESERVED.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE COMPANY'S TOTAL LIABILITY TO YOU FOR ANY CLAIM ARISING FROM THE SERVICE SHALL NOT EXCEED THE AMOUNT YOU PAID US IN THE 3 MONTHS BEFORE THE CLAIM AROSE. WE ARE NOT LIABLE FOR INDIRECT, INCIDENTAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOST CREDITS, PLACEMENTS, OR DATA.
You agree to indemnify and hold the Company harmless from any claims, damages, or expenses (including attorneys' fees) arising from your use of the Service, your content, or your violation of these Terms.
Any dispute arising from these Terms or the Service will be resolved by binding, individual arbitration rather than in court, except you may bring an individual claim in small claims court. You and the Company each waive the right to a jury trial and to participate in a class action or class arbitration. You may opt out of this arbitration clause by emailing the contact address above within 30 days of first accepting these Terms, stating your intent to opt out.
These Terms are governed by the laws of the State of Florida, without regard to conflict-of-law principles, except where the arbitration clause above requires application of the Federal Arbitration Act.
If any provision of these Terms is found unenforceable, the remaining provisions remain in full force.
We may modify these Terms at any time by posting the updated version in the Service. Material changes will be noted with a new effective date. Continued use after changes take effect constitutes acceptance.
