Treasure of the Ancients is the very first world in the game, so you can get this achievement straight away.
To unlock it you have to line up 5 Jaguars (with wilds symbols working as jolly).
The game doesn't calculate a row as a straight line, infact this is how I unlocked it
If you look at the screenshot, there is a line (I've marked it red just to make it pop out) passing trought 5 jaguars/wilds icons. That's the "row" you are looking for!
