Is dominoes luck or skill?
Any single hand of dominoes can be won by a lucky draw. Almost no match is - and the difference between those two sentences is where the game lives.
Where luck lives
The shuffle deals you seven of 28 tiles, and sometimes those seven are simply bad: one suit missing entirely, or a fistful of heavy doubles. In drawing games the boneyard adds more variance - a bad dig can bury you in dead tiles. Over one hand, that noise is loud, which is exactly why serious dominoes is always played across many hands.
Where skill lives
Skill is everything the shuffle doesn't decide: knowing that each number sits on exactly seven tiles and counting them as they land, remembering which suits your opponent passed on, steering the ends toward numbers they can't answer, and timing scores in All Fives so the count lands on your multiples, not theirs. Strong players win blocked hands on purpose, not by accident.
The long game evens it out
Across a race to 100, 150 or 61, the draws average out and the decision quality compounds - the same reason poker professionals beat the field over a season. If you want the most skill per hand, play Fives and Threes, where every tile is a two-way arithmetic problem, and see how to win more often for the habits that matter.

How do you win dominoes more often?
Play your doubles early while they still fit, keep a spread of suits so you always have an answer, and count what's been played - each number appears on only seven tiles. Note every pass, steer the open ends toward suits your opponent lacks, and in scoring games think in multiples.
Why do you count pips in dominoes?
Pips - the dots on each tile - decide everything the last tile doesn't. Blocked hands go to the player holding fewer pips, hand winners score the loser's leftover pips, and tracking which pips have been played tells you exactly what remains unseen. Counting them is the core skill of the game.
