Pick & Roll：籃球自走棋 is a free, non-commercial fan project. It is not an official NBA game and has no paid content.

It is not affiliated with, authorized, sponsored or endorsed by the NBA, NBA Properties, the NBPA, or any team, player, coach or their representatives.

Names of players and coaches, and team names, abbreviations and colours, belong to their respective owners. They are used for identification only and do not imply that anyone took part in, approved or supports this game.

Player figures are simplified, toy-style 3D models built procedurally by RZhang Studio; no official photos, game footage or broadcast material is used. No official NBA or team logos are used [to be confirmed before release].

Player ratings are game-design estimates derived from public statistics. They are not official ratings and are not a judgement of any player's real ability.

The eight league teams in the game, including yours, are fictional and unrelated to any real team.

Match results are simulated by the program and neither represent nor predict real games. The game is provided "as is", with no guarantee that it is uninterrupted or error-free.

Online play

In online play the match is computed in one player's browser, shown as the host. Version 1 cannot prevent that player from altering results, so please play with friends you trust. There are no leaderboards or records that need fairness guarantees.

Pick & Roll：籃球自走棋 is made by RZhang Studio and uses the open-source software and fonts below. The full license texts are included on this page.

Made by

© 2026 RZhang Studio. Game code, player models and animations, the arena, portraits, UI icons, sound effects and music are made by RZhang Studio: player models and animations are built procedurally in Blender, the arena is assembled by the game code, icons are drawn as code vectors, and the sound effects and music are synthesized by code.

All sound effects and music in the game (court and crowd sounds, UI sounds and the background music) are generated procedurally by the project's own script, scripts/build_audio.py; no third-party, downloaded or stock audio is used.

Player ratings are derived from public statistics; the sources used for each player are recorded in the game data file player_research_v3.json.

Game engine

Built with Godot Engine 4.7.2, released under the MIT license. Copyright (c) 2014-present Godot Engine contributors (see AUTHORS.md); Copyright (c) 2007-2014 Juan Linietsky, Ariel Manzur. The full MIT license text follows.

Godot Engine includes the third-party components below (for example FreeType, HarfBuzz, ENet, Mbed TLS and zlib), each under its own license; the list and the license texts come from the engine itself.

Portions of this software are copyright © 2025 The FreeType Project (www.freetype.org). All rights reserved.

Fonts

The UI font "Courtside Sans TC" (Medium 500, ExtraBold 800) and the player-ID font "Courtside Sans TC Names" (Bold 700) are subset, static-weight and renamed derivatives of Noto Sans TC, licensed under the SIL Open Font License 1.1. Original font Copyright 2014-2021 Adobe (http://www.adobe.com/), with Reserved Font Name 'Source'. They were renamed to respect the OFL Reserved Font Name rule. The full OFL text follows.

Web runtime

The web build of the engine is compiled with Emscripten. The Emscripten runtime (index.js and the system libraries inside the WebAssembly) is dual-licensed under MIT and the University of Illinois/NCSA license and is used here under MIT; the bundled musl libc is MIT-licensed, and LLVM's libc++, libc++abi and compiler-rt use the Apache License 2.0 with LLVM Exceptions. The texts are in legal/THIRD_PARTY_LICENSES.txt on the website [to be checked against the exact Emscripten version].

The web shell and the relay code are written by RZhang Studio and use no third-party JavaScript libraries; any added later will be listed here.

Tools and services

Tools used to make the game (not distributed with it): Blender, Python with fontTools and NumPy, and Node.js. Python's built-in Big5/GB2312 codec tables are only used to generate the list of characters allowed in player IDs.

Online service: Cloudflare Workers and Durable Objects (Cloudflare, Inc.).

This notice covers the web version of Pick & Roll：籃球自走棋 at https://pickandroll.rzhangstudio.workers.dev, operated by RZhang Studio. There are no accounts or logins, and we do not collect your real name, e-mail address or phone number. There are no ads, analytics or tracking tools, and our code sets no cookies [to be confirmed: whether Cloudflare's security features set necessary cookies].

Stored in your browser

Your player ID (2–6 characters), kept until you change or clear it.

A resume record (room, seat, room code and a resume token) so you can return to your seat after a reload or a disconnect; cleared when the match ends, when you leave or are removed, when the room closes, or after 3 hours.

A local continue save, created only when you are the last human in a room and the match continues on your device; cleared when that match ends.

A device benchmark result and how often you hosted in the last 24 hours, used to choose which browser hosts a match.

Settings such as quality and install prompts, your solo season save, and a cache of game files for faster loading. Online features never read or write your solo save.

This data lives in your browser's localStorage and site storage, separately for each web address, and we cannot see it. You can delete it in Settings → Clear local data, or by clearing this site's data in your browser.

Processed during online play

The data below is processed only when you use online features (checking a new ID, creating or joining a room, playing a match), and only to run the match (including host migration) and to prevent abuse. Without an ID you cannot play online, but solo play still works.

Your ID: sent when you create or join a room and stored in your ticket and the room's seat list. It may also be sent when you choose an ID, to check that it can be used, and is not logged.

Connection data: Cloudflare and our front-end code briefly see your IP address. We keep only a code computed from it with a key that changes daily, for rate limits (minutes), abuse blocks (10 minutes) and a room's kick list (until the room closes). Our code never logs the IP address itself.

Your continent and Cloudflare data-centre code, used only to place the room's relay and for room statistics.

Device type (desktop, tablet, Android or iOS), benchmark milliseconds and recent hosting count, used only to choose the host. No browser user-agent string or device model is sent.

Gameplay commands and match progress: the server keeps per-round checkpoints and a command log so that another player can take over if the host drops. Resume tokens are stored on the server only as hashes, and the host never sees them.

When a room closes (at the latest 3 hours and 10 minutes after it was created), all of its data on the server is deleted.

What other players see

Players in the same room see your ID, seat, team and match performance. Room previews by code or link show no IDs. Please do not use your real name or contact details as your ID.

The host's browser temporarily holds every player's game state and ID for the match. The host is one of the players in the room, so please play with friends you trust.

Logs and service provider

Our code writes no server logs (Cloudflare observability is turned off); its output contains only room ids, seat numbers, counts and timings.

The website and the online service are provided by Cloudflare, Inc. When you download the game (including for solo play) or play online, connection data passes through its global network under Cloudflare's privacy policy: https://www.cloudflare.com/privacypolicy/

Children

The game is rated 普遍級 (general audiences). Children should play with a parent or guardian and keep an eye on playing time.

Your rights and contact

Under Taiwan's Personal Data Protection Act you may ask to review, receive a copy of, supplement or correct, stop the collection, processing or use of, and delete personal data about you. There are no accounts and room data is deleted when a room closes, so most data exists only in your browser, where you can delete it yourself; for anything else write to rzhangstudio@outlook.com.
