Demon666 can you fix it

Build john Conway's game of life
Will be difficult because of math and logic and because of the amount of calculations that have to happen at once
Info the game is very simple: you place down cells and if any of the following rules happen then the cell changes:
Acording to wikipedia
The universe of the Game of Life is an infinite two-dimensional orthogonal grid of square cells, each of which is in one of two possible states, alive or dead. Every cell interacts with its eight neighbours, which are the cells that are horizontally, vertically, or diagonally adjacent. At each step in time, the following transitions occur:

Any live cell with fewer than two live neighbours dies, as if caused by under-population.
Any live cell with two or three live neighbours lives on to the next generation.
Any live cell with more than three live neighbours dies, as if by over-population.
Any dead cell with exactly three live neighbours becomes a live cell, as if by reproduction.

The initial pattern constitutes the seed of the system. The first generation is created by applying the above rules simultaneously to every cell in the seed—births and deaths occur simultaneously, and the discrete moment at which this happens is sometimes called a tick (in other words, each generation is a pure function of the preceding one). The rules continue to be applied repeatedly to create further generations.
My challenge
Must have a pause button to place cells
Tapping a empty grid spot fills it
Clicking a full one erases it
does not work if the equations don't calculate simultaneously

i cant figure it out why it no work
