Your goal in Link It 4, which debuted as Cuatro, is to create a line of four roof tokens before anyone else.
On a turn, roll five dice up to five times, trying to get dice combinations visible on game board spaces. You can keep and re-roll dice as you wish, but the more you roll, the more restricted you are in where you can place a roof. Roll five times, for example, and you can place a roof only on an empty space, whereas if you roll four times, you can place a roof on an empty space or a space that already has one roof on it. If you can't place a roof anywhere, you discard one from your supply.
If a player ever has a line of four visible roof tokens, whether diagonally or orthogonally, they win immediately. If a player has a roof token on all three jackpot spaces — which require a five-of-a-kind — they win immediately, no matter where those tokens are in the stack. If no one meets either condition before everyone runs out of tokens, players score for their placed tokens — 5 points for a roof at the fifth level, 4 points at the fourth level, etc. — and whoever scored the most points wins.
