Tips tranquility

I] Beginner part:

Try to create a gap of 1 card (or 3, 5, 7, 9...) when you put a card, that way less cards will be discarded.

There is 80 numbers and 36 places, this means the difference between two cards is in average 2,22. Which means the difference between two cards separed by 1 tile is in average 4.5. The difference between lines is 13.33.

Putting a 2 turn 1 at the second step is pretty good. It will force the player who will drew the 1 to play it here and to keep it, but you will get a slight advantage on the following steps.

II] Advanced part: Early on (before any discard!), putting a 18 four step after a 13, will force people to keep their 14/15/16/17, but if 15 or 16 is drawn first it can be put in the middle, and if 14 or 17 is drawn first, it can be hold or played immediately. You could do that one or two times, but not much more, at one point, you will force players too much into playing in those things. Of course, this doesn't work if there is card missing in the deck.

If some cards are missing, when you start, you can expect everyone to play their 1 (or 80) in priority (so at 4 players, turns 1~4). Which means, if you have a 2 (or 79), you should wait until everyone played once before playing that 2 during the second turn (so at 4 players, turns 4~7). And same for the 3 (for 3/78 turns 7~10) even if holding the 3 isn't bad.
