VoodooDreams does not have an iPhone app, so on iOS you play in the browser. The mobile site is how you reach VoodooDreams from an iPhone, and there is nothing to download from the App Store. Open the site in Safari, then log in or sign up from there. This page explains what playing on a phone involves and what to check before you start.
What you can do on your phone

The mobile site is the phone version of the VoodooDreams website, opened through your browser. You can log in, browse the games shown on the mobile site and play from the same page. Because there is no separate app, there is no extra menu or install step to learn. You use the site the way you use any other web page on your phone.
The main difference from a computer is the screen size. Game menus, buttons and the cashier section are smaller, so take a moment to find the controls before you put money on a game. Play is also tied to your connection, so a weak signal can interrupt a round. If a game does not load, refresh the page or check your connection. Do not assume a game is available on the phone just because it is listed on the desktop site.
If you want to start from the beginning, you can sign up on your phone in the same browser.
Playing in Safari on iPhone

There is no VoodooDreams iPhone app to find or install. If you search the App Store, you will not find a VoodooDreams app to download. Be careful with any app that claims to be VoodooDreams but comes from a different source. Only use the mobile site, opened by typing the address you know or from a bookmark you saved yourself.
Safari works best when iOS is up to date, so update your phone if the site feels slow or a page does not display properly. Use Wi-Fi where you can, or mobile data with a clear signal. The site needs a live connection, so there is no offline play and nothing is stored on the phone to continue later.
A shortcut added to your home screen is only a bookmark to the website. It does not turn the site into a native app and does not change what you can do on it. If you use one, check that it opens the correct address before you log in. For account access, go to the login page.
Keeping your account and money safe on a phone

Start with the device. Set a passcode or use Face ID, and do not share your phone with others while you are logged in. If the phone is used by someone else, log out after each session and do not let the browser save your password on that device.
Watch out for messages that ask you to click a link to access your account. Type the address yourself, and do not enter your details on a page reached from a text or email you did not expect. Avoid logging in over public Wi-Fi, and do not take screenshots of your account details.
Mobile data is worth keeping an eye on. Game sessions and live streams use more data than browsing, so check your data allowance or use Wi-Fi for longer sessions. Set a budget before you start, not during play, and keep to it.
