The game is extremely situationnal, before playing any card, try to see what you can do with your hand.

You want at best to have lines which cover most range of numbers. Per example if the rightmost card of a line is 3 and another is 9, you kinda have the ranges from 1~5 and 7~11, which mean starting a line with a 6 or a 12 has more value. Looking at the tiles already played, you can sometimes deduce which numbers are in most copies in decks. At 2 or 3 players, when you start a line, try to have another tile to play next to it. Try to put low value on lines (since you can't play low value in high line) but don't force it, having different ranges is usually better.

After a bridge, there is value on putting the same color just after the bridge (easier to fill the bridge), especially if the numbers are far from each other. It's possible to play an 11red after a 5red and a bridge: when you will play a 8 to fill the bridge, you will discard 3 cards. Note it's not advised, so you should have strong reasons to do it.

If your opponent discard a lot to play a tile or started a new line, there is an high chance he got a similar number to play next to it. Especially at 2 players, if you don't have the same number and you can let him have one turn to play it, it's great.
