Roll It is played with your phone and computer at the same time. You'll use your phone to toss a virtual ball onto your computer screen. Your computer (a desktop or laptop) must have an internet connection and run a modern Web browser like Chrome. If you're reading this you're probably off to a good start (How do I get Chrome?). First, load Roll It on your computer's Web browser. Second, follow the onscreen instructions to get your phone and your computer talking to each other. For a browser game, Roll It is heavy on the 3D graphics. Using a peppy computer will make for a better experience.
Rules of the game
In every round, each player has nine balls to roll—one at a time—down a ramp. When the ball reaches the end of the ramp it will fly up toward the backboard and (hopefully) land in one of the numbered cups. Sink a ball in the cup labelled "100" and you'll win 100 points. Not a bad deal. Roll a perfect game by sinking all nine balls into a "100" cup for a grand total of 900 points. Once you've played a round you'll have the option to advance. With every new level comes new backboard configurations and special moves.
Grab your smart phone
To play Roll It your phone must have an internet connection and run a modern mobile web browser like Chrome, so try an Android or iOS device. (How do I get Chrome for mobile?) Your phone can probably connect to the Internet over a cellular network like 3G or LTE, but good old wifi is probably the fastest and most reliable (And you won't risk any expensive data plan overages). Your phone must also contain a special piece of hardware called an accelerometer which is able to detect the orientation and movement of your phone through space. If your phone can run Chrome then it probably has an accelerometer.
Open your mobile browser
Roll It is a website, not an app, so all your phone needs to play Roll It is a mobile browser. Any modern mobile web browser will do, but Chrome for Mobile works best—and it's free. (How do I get Chrome for mobile?) Once you have Chrome open on your phone you're ready to sync your phone to your computer.
Sync your phone to your computer
Your phone needs to tell your computer where you're aiming and when to roll the ball. That's where syncing comes in. Roll It handles syncing by using game codes—five random letters that act as a secret password between your phone and your computer. As you click through the Roll It website on your computer you will arrive at a Controller Setup page with an illustration of a phone and your unique game code. Syncing your phone to your computer is an easy two step process:
1. Type http://g.co/rollit into the address bar of your phone's mobile browser.
2. Once the Roll It site loads on your phone it will ask for your unique game code. On your phone enter the five-letter code that's displayed on your computer screen.
Syncing can take a few moments so you might use this time to practice your swing. Once your phone is synced, you'll see a big thumbs up on both devices. Remember, your phone can probably connect to the Internet over a cellular network like 3G or LTE, but good old wifi is probably the fastest and most reliable (And you won't risk any expensive data plan overages).
Pro-tip: rotation lock
Roll It assumes that you are holding your phone in portrait—rather than landscape—orientation. If at any point in the game you rotate your phone into a landscape orientation you'll receive a warning message requesting that you rotate back. To avoid this altogether you can lock the rotation of your phone.
For Android (Jelly Bean, version 4.2): Open the notification shade by swiping down from the top of your screen. You will see a list of icons at the top of the screen. Tap on the rotation lock. The rotation lock is the icon on the far right with a circular arrow. Your screen will lock in its current orientation, so make sure your phone is in portrait orientation when you do this. Tap the rotation lock icon again to release it.
For iOS: Double tap your home button to bring up the list of open apps. Swipe the row of open apps to the right to reveal the controls for rotation and music on the left. The rotation lock is the gray icon on the far left with a circular arrow. Tapping it will cause a lock to appear on the icon. Make sure your phone is in portrait orientation when you do this. To unlock your rotation just tap the icon again.
Select number of players
Now that your phone is synced to your computer you should see a yellow ball on your computer's screen. It rolls to the left or right depending on the angle of your phone. Tilt your phone to the left to roll the ball to the left. Tilt your phone to the right to roll the ball to the right.
Even if you select two or three players one phone is all you need. (You'll simply pass your one synced phone back and forth—so make sure you trust your friends' grip.)
Menu selection. Roll It's menus use the rolling yellow ball to make selections. Hold your phone vertically with the screen facing you. Then tilt your phone slightly until the ball rolls and a different option is selected. When the option you want is highlighted tap the button on your phone's screen and you are good to go.
Touch to aim. Before each roll you'll notice a dial at the top of your phone's screen. To aim simply touch and drag the pointer across the dial. As you move the pointer an indicator on your computer's screen will rotate as well, indicating the direction you are aiming.
Swing to roll. Once you've aimed you're ready to roll. Grip your phone tightly—we don't want any phones flying through the air—then swing your arm in an underhanded arc toward your computer. Then a ball will come rolling up the ramp on your computer's screen. Remember, it's all in the wrist, not the biceps. Practice makes perfect.
