Why Copies Put the Login First
Because for a copy, the login screen is the product. Building a convincing timed-round game takes work; building a form that harvests an email address, a phone number and a reused password takes an afternoon. That difference explains the pattern precisely: genuine builds are relaxed about letting you look before you commit, and copies are impatient to collect your details before you notice the game behind them is thin.
It also explains why "login" searches for this format are so heavily targeted by pages that are not operators at all. Somebody looking for a login screen has already decided to sign in somewhere, which is the most valuable moment in the entire funnel.
If You Registered Somewhere You Should Not Have
Change that password anywhere else you have used it, starting with email and banking. Assume the address and number are now on a marketing list, and treat unexpected "account verification" messages as hostile — they are the standard follow-up, timed to arrive while the registration is fresh enough to seem plausible. If you granted an app SMS or accessibility permission during the process, revoke it, uninstall, and change the important passwords from a different device.
Before creating an account anywhere, it is worth knowing what the game does with money: the big small game guide covers the round and the payout. If you have not staked yet, the demo notes explain how to practise without an account at all.
