1: The numbers in the game will continue to rise upwards. Once any line touches the top of the screen, it will be gameover.
2: You can drag a number onto another adjacent number. If the two numbers overlap and add up to less than 10, the number will be synthesized by adding two numbers. For example, dragging 1 to 2 will form 3; if there are 3s adjacent to the formed 3, the adjacent 3 will be eliminated together with the newly formed 3.
3: If the sum of two numbers is greater than 10, the positions of the two adjacent numbers are exchanged. For example, if you drag 7 onto 8, the resulting number is 15 greater than 10, then 7 and 8 exchange positions.
4: If the sum of two numbers is equal to 10, then 10 will become a bomb that blows up all numbers within a 3X3 range around itself.
5: Resurrection can be digitally rolled back 8 lines.
