Spaceball XO feels like your familiar tic-tac-toe game - with a rolling ball and a cosmic twist! Form three planets in a row by rolling the green ball onto the winning space. Vertical, horizontal or diagonal line, you win! Spaceball XO turns into a tricky maze of planets and stars. Navigate the green ball along the maze until it lands onto the winning square. Watch out! Blocking two yellow stars from forming a line ends your turn. You can play Spaceball XO on Classic mode or Plus mode. You have three ball attempts to complete 30 levels on Classic mode (it’s free)! The game gets more fun and challenging when you upgrade to the Plus version. Pay only one time to activate the Plus mode and get all its features, including the following: 1. Encounter a red exoplanet when you reach certain scores. Collect the exoplanet to earn an extra life. 2. Press a nuclear button to blow up the maze and uncover the winning space. Earn an extra nuclear button every time you complete ten levels. 3. Earn game points upon completing each level. Play to beat the high score! Get Spaceball XO today!
