3. Free Tiles:


The last heuristic is simply to keep your board from getting too cramped. Players lose when they keep too few tiles free of numbers, and the new tiles that generate cannot be matched with anything. Simply try to keep your board as free as possible, and never let yourself fall into the trap of having only one tile free!

The screenshot below shows how you should not let your board end up like.

So, take these methods into account when playing the game. Before you make each move, think of these questions:

  • Is my board monotonic?
  • How can I make it monotonic?
  • Which move would match the greatest number of tiles?
  • Do I have plenty of space for new tiles to generate?
