20-Coin Hexes are a type of Hex which appear in Mario Party DS.
Description[]
As with any other Hex, a 20-Coin Hex can only be obtained from a Hex Area at random by whoever passes by there. A 20-Coin Hex can be placed on a Blue Space or Red Space up to five Spaces from the user. The 20-Coin Hex is an equivalent of the 10-Coin Hex in that it steals Coins, twenty in the 20-Coin Hex's case, from an opponent to give to whoever placed it or their team. If the user or a teammate lands on a 20-Coin Hex, they instead receives five Coins. Like any other Hex, after the 20-Coin Hex is activated, the Space that it was on returns to normal.
