The sideways 8 is the sign for INFINITY,but your wasting your time.i had the sign for infinity for months.You only need to merge 2 together,Merging lots will give you the same score,but cheats have taken over across the world.I worked my way up to 95 global and within 2 days i am now 4500th globaI.I have stopped playing now.

Your score increases every time you merge infinity tiles! It’s all good.
