Most of a pool game never needed an account. Shooting against the computer, passing the phone across the table, and practising on an open rack all run entirely on the device in your hand, with nothing to prove to anyone. A login is only genuinely required for two things: playing a stranger online, and carrying your progress to another phone. Every other sign-in prompt is there for the publisher, and you are allowed to say no.
01
What an account actually does in a pool game
Strip the marketing off and an account does four jobs. It gives the game a stable identity to match you with opponents. It gives it somewhere to store your progress that is not the phone, so a new device can pick up where the old one left off. It gives the publisher a permanent address for notifications, offers, and win-back emails. And it gives them a durable way to attach purchases, refunds, and bans to a person rather than a device.
The first two are for you. The second two are for them. A game that lets you play the computer without signing in has decided the first two are enough. A game that locks the whole menu behind an email field has decided they are not, and that tells you a lot about what the rest of the experience will optimise for.
02
The parts of pool that never needed one
Physics does not care who you are. A cue ball struck low with the right speed draws back whether or not a server has verified your email, and a computer opponent only needs the table state to pick a shot. The entire single-player side of pool, from the opening break to the 8-ball, is a closed loop between your fingers and the simulation.
Pass-and-play is the same. Two people, one phone, alternating turns: the game needs to know whose turn it is and which group each player owns, and both of those are decided at the table. Practice mode is purer still. There is no opponent, no score, and no reason for the game to know anything beyond where the balls are.
Ask what information the feature in front of you actually requires. If the answer is “the position of sixteen balls,” an account is not a requirement. It is a choice someone made on your behalf.
03
Game Center: the login you already have
Online play is the one place identity is unavoidable, because the other player needs to know they are facing the same person for the whole match. The question is whose identity. On iPhone the answer already exists: Game Center is Apple’s system-level player profile, signed in once in Settings and available to every game on the device.
When a game uses it, the game receives a player identifier and the nickname you chose, and nothing else. No email, no password, no recovery questions, no new thing to forget. If you are already signed in, a Game Center game simply works online. If you are not, the phone offers the sign-in sheet once and you can dismiss it and keep playing offline. That is the whole cost.
Compare that with a publisher account, which lives on their servers under an email, a phone number, or a social login you created for one game. It follows you only to other games from the same company, it needs its own password, and it is the thing that gets leaked when a studio has a bad week. Sign in with Apple sits between the two: it creates a publisher account but lets you hide your real email behind a relay address, which is worth using whenever a game offers it.
04
What you honestly give up by skipping it
This is not an argument that accounts are worthless. If your progress lives only on the phone, then losing the phone loses the progress. Coins, unlocked cues, and a settings screen you have tuned to your liking do not travel to a replacement device by themselves. Online matches are off the table too, by definition.
The honest design is a game that takes the backup problem seriously without inventing a login to solve it. On iPhone that means saving progress to your own iCloud when you are signed in, and carrying on locally when you are not. Your data stays in your storage, under your Apple ID, and the game never had to ask for anything.
What you should be suspicious of is the reverse: a game that will only back up your progress to its servers, under itsaccount, and warns you in red that declining means starting over. That is not backup. That is a reason to hand over an email address dressed up as a safety feature.
05
How to check before you download
The App Store listing tells you most of this if you read it from the bottom up. Start with the App Privacy section. “Data Not Collected” almost always means no account, because there would be nothing to link it to. “Data Linked to You” with contact info and identifiers listed means an account exists somewhere, whether or not it is mandatory.
Next, the Information block near the bottom. If it says Game Center is supported, online play likely runs on Apple’s identity rather than a custom one. Then the screenshots: a welcome screen with an email field in the first frame is a confession.
Finally, the reviews, sorted by most critical. Search them mentally for “login,” “sign in,” and “account.” Forced accounts generate one-star reviews faster than almost any other design decision, and players describe the exact moment the wall appeared. That is more reliable than anything the description claims.
Open the game. Dismiss anything that asks you to sign in. Try to start a match against the computer. If a table appears and the break goes in, you have a game that respects the distinction. If the menu is greyed out or the sheet comes back, delete it; it will not get better from here.
06
The patterns that mean no
The wall before the first shot. Any sign-in that precedes single-player play is a wall, however politely it is worded. A real reason to sign in can wait until you tap the online button.
Guest mode with a timer. Some games let you play as a guest and then remind you every few racks that your progress is “at risk.” The risk is manufactured: the game could back up to iCloud and chose not to, so that the nag has somewhere to point.
Rewards that need linking. If the daily reward, the free cue, or the welcome coins only unlock once you “link an account,” the reward is bait. Fixed, published rewards that every player receives do not need to know who you are.
Email only, no Apple option. A game that offers Facebook and email but not Sign in with Apple is choosing the login methods that give it the most data, and iOS rules require the Apple option alongside third-party social logins, so its absence is worth noticing.
07
Where our own game sits
Duel has no account of its own. Computer opponents, pass-and-play, and practice all work with nothing to sign into, from the first launch, with every reward published as a fixed number that does not change based on who you are. Online 1v1 runs on Game Center, so the only identity involved is the one Apple already manages for you, and the game never sees an email or password.
Progress is backed up to your own private iCloud when you are signed in, and stays on the phone when you are not. We think that is the right shape for a pool game: the physics is the product, and the physics never needed to know your name.

Common questions
Do you need an account to play pool on iPhone?
Not for the parts of the game that run on your phone. Playing against computer opponents, passing the phone to a friend, and practising on an open table need no identity at all, so a game that demands sign-in before any of those is asking for its own benefit, not yours. An account only becomes genuinely necessary when you want to play a stranger online or carry your progress to a second device.
Is Game Center the same as creating an account?
No. Game Center is Apple’s built-in player identity, signed in once in Settings and shared by every game on the phone. A game that uses it receives a player ID and your chosen nickname, never your email address or a password, and there is no new login to remember. A publisher’s own account, by contrast, lives on that publisher’s servers under an email, phone number, or social sign-in that you created for one game.
What happens to my progress if I don’t sign in?
It stays on the phone, which is fine until the phone is lost, replaced, or wiped. Without some form of backup, coins, unlocked cues, and settings do not come with you to a new device. The honest middle ground is a game that backs progress up to your own iCloud when you are signed in and keeps playing locally when you are not, rather than one that holds your progress hostage to its own servers.
Why do mobile games make you log in?
Four reasons, and only two help you. An identity lets the game match you with opponents online and sync your progress between devices. The other two are a permanent contact address for marketing and re-engagement, and a durable way to tie purchases and bans to a person. When a game forces a login before single-player works, the second pair is usually the real motive.
How can I tell if a game needs an account before downloading?
Read the App Store listing from the bottom up. The App Privacy section says whether data is linked to you, which is a strong hint that an account exists, and the Information block lists whether Game Center is supported. Then skim the one-star reviews for the words login, sign in, or account; forced accounts generate complaints faster than almost any other design choice.
