If you use the original, you can open a new tab and then go to that one later on if you mess up your game on the original. That is cheating though.

I understand now. It's not cheating to undo moves but it is cheating to change to a game where you can undo moves.

Whaa?

Can we just say your original post was "Why would you waste so much time undoing moves for a good score?" or something?

Yes. Please answer that question. There is no point IMO getting a good score if you undo moves to accomplish it. It's similar to taking apart a scrambled cube, rebuild solved then start and stop a timer as quickly as possible and note down the time.

This is a theory session on what I call the 2048 parity problem.
If you don’t already know what 2048 is, it is an online game/puzzle that spawns in new blocks in a 4x4 grid, and you have to slide them together to make larger numbers. Each number is multiplied by 2, ex 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048. The only two blocks that get spawned in are 2 and 4, so it is a little unpredictable where the number will spawn and what number it is.
anyway, the way I play 2048 is that I some numbers in the beginning and slide them to the top left, creating even larger numbers. However, I can use only left and up, sometimes right, but rarely down. What happens is that the game will sometimes end up where I cannot move left and up, or even rarer, left, up, and right, forcing me to move left and spawning a number in the top left position, or moving down and the said thing happens. What is the best solution for this problem so that you can keep playing for as long as possible, yet save that top left corner? This can also happen with the 2nd, 3rd or even 4th rows, although it is rare.

That doesn't exactly have anything to do with parity. (?)

The spawn rates are 90% for 2 and 10% for 4, iirc, so while it's random, it's still fairly predictable. Try to keep your board in a state where you can merge in large numbers when you need to, I guess. (It's a bit difficult to concretely describe strategies because it ultimately boils down to "think about what can happen, and try to avoid bad things happening", where determining how good/bad a board state is largely based on intuition you build up from playing lots of games and dying lots of times. There isn't really a concrete rule.)
