Slot Synch is a 2-vs-2 minigame in Mario Party 3.
The players on each team attempt to match both of their blocks to get points by hitting the block to stop it on a character to match it together. A Goomba is worth one point, a Koopa Troopa is worth two points, Toad is worth three points, and Baby Bowser is worth −1 point unless the team has no points to subtract. The team that has more points at the end of the minigame wins. If both teams have the same number of points when the time runs out, the minigame ends in a draw.
On the board showing the points for each character, the Goomba and Baby Bowser are listed as being worth "1 pts" and "−1 pts," respectively, when the correct way of writing these is "1 pt" and "−1 pt." If a partner is a computer AI player, they always match a human's result.
