Long Paths
Each time you place a tile, you extend your line by at least one tile length. With luck and planning, however, you can make it go farther. To do this, you must choose a pathway on the active tile that will feed your line into another tile you have already placed. Your line always goes as far as it can on each turn, stopping only at an empty space on the board, where there is no more path to continue along, or at a game-ending obstacle such as a wall or the starting tile.
Scoring
The key to high scoring in "Entanglement" centers on building long additions to your line in a single turn. When you place a tile, you receive 1 point for adding the first tile length to your line, 2 points for crossing into a second tile, 3 points for crossing into a third and so on in a simple mathematical progression. Since each tile has six pathways, you can potentially reuse the same tile more than once in a turn if the pathways permit it. The important thing is for your line to cross the boundary from one tile into another. Thus, if you place a tile that causes your line to cross four tiles, you get 10 points: 1 plus 2 plus 3 plus 4.
Path Planning
With "Entanglement," you have to plan ahead to get the best results. Rather than taking the highest possible score each turn, sometimes it pays to take a few low-scoring turns in exchange for setting up an especially long series of pathways, into which you may then be able to feed your line all at once. It also takes planning to avoid cornering your line on the board. Because you can build your path in whatever shape you want, you have to take care not to prematurely end the game by cutting off your options too early. Try not to divide the empty spaces on the board from one another unless there are pathways connecting them.
Randomness
You can control which pathway you choose for your line, from the six available pathway options, by rotating the active tile before committing it to the board. However, you can̵7;t control which tile you actually receive each turn. The game determines this randomly, out of 1,799 possible tile configurations. To complement this randomness, you also get a reserve tile, in the bottom left corner, which you may swap out with an active tile whenever you wish. The active tile then becomes the reserve tile until you decide to swap it out again.
