Also the Fibonacci and 243 variants are hard!
Now a game 'inspired' by 2048:
Link: Darling [Odd name for this game, I thought]
There are no rules/explanation of game play. Here is how it seems to work:
Click on a square where there are squares with the same digits sitting adjacent. The square that is clicked on 'inherits' the sum of the values in the squares that were in contact. The other squares disappear and are replaced with squares with new values falling in from above.
Build your bonus. Use it to change the value of a square when you have problems making a valid move. Using a bonus uses the entire value of that bonus.
Get to 5000 points.
That's it [I think?]
My wife and I are both hooked on this game. Best score so far is just over 18k
