Graphic Enhancement To The Winning Paylines Indicators
Add some sparkle to the lines, maybe border them in glittery pixels, to add a little more “excitement” to the winnings. Have alternate sprites for the existing tiles that can “flash” or “glow” to highlight a tile that is part of a winning payline. The flashing or glowing could even be appropriate to the game’s theme.

Symbol animations are on several themes, and will be added to the rest in the next update.

to many graphics slow the games. sorry to mention other games but it proves my point. i played Zynga games on FB, at first they were ok, then they added so many things that it stopped loading all together. now i cant play them.
