Swipe numbers around the board until you make a match of three or more of the same numbers. Once this happens, the group of numbers will merge and one of the merged numbers will increase in value by +1.
Every game begins with 20 moves. Use all of these moves and the game is over. You can earn additional moves by merging groups of 4 or more numbers. Groups of 4 numbers will earn you +1 move. Groups of 5 numbers will earn you +2 moves. And so on...
You earn points for every merged group of numbers. Your points are determined by the sum of the merged numbers, and the total number of merges. What's your high score?
Use powerups to move numbers, destroy numbers, and so much more. The more you play, the more you earn power ups. Use them wisely!
See how you compare against other people playing SUM. The leaderboards not only contain scores but also the highest numbers merged. Log into Facebook and compete against your friends.
Play for 5 minutes or for 5 hours. There's no time limit. There's no rush. Play while listening to a podcast or your favorite tracks, on your way to work, or while binging your favorite show.
The interface is intentionally minimal. Your points will increase as your merge numbers. Your total moves will decrease whenever you swipe numbers. As you merge numbers, the formula to determine your rewarded points appears above the numbers. And, if you're curious to know how you're doing compared to your high score, there's a progress bar underneath the points and moves.
The game board consists of numbers ranging from 1 to 6. You can swipe any number in any direction, BUT pay attention to your remaining moves. When you hit 0 moves, the game is over. As numbers are merged, the remaining numbers on the board drop down into positon and new numbers drop onto the board from the top. These new numbers will have a value of 1 to 6.
If you're in a jam, use your power ups. To use them, tap the "power-ups" tab at the bottom of the screen. The power up tray will appear. Feel free to use any of the available power ups found in this tray. As you play the game, you will be rewarded with random power ups. So keep playing!
