2048 craft

Noob needs to open all the known blocks! The size of the field is 4 by 4. Your goal is to get a block with the number 2048. If two blocks have the same number, then they can be added together and get a number twice as large!

Use swipe to move around the field.
When two tiles with the same denomination touch, they merge into one.
The win is counted when the result is 2048.
