Point Activity Pastime Game ~ BoxMerge

It's a game where you merge the same numbers to make them bigger and bigger. It's not exactly a strategy guide, but for example, if the number you want to change is in the back, you can aim for a moment when the number in front of it changes and bounces up to change the one in the back. Or, if two same numbers are already close together and the number you're aiming for is nearby, you can aim for the corner of the two close numbers, merge them, and use the rebound to make your target number bigger. It's not difficult, but it's a game where you can enjoy seeing how big you can make the numbers.
