Among the many collectible currencies in Sonic Frontiers, Gold Cards are likely one of the most challenging to obtain. Similar to Purple Coins, Gold Cards are voucher-like tickets that only serve the singular purpose of earning valuable prizes from Big the Cat's shop. For newcomers unfamiliar with Big, he is a large purple cat comfortably trapped within the Cyberspace dimension. Instead of fretting about his situation, Big spends his time catching fish in the lakes and ponds within Cyberspace. After Sonic encounters Big for the first time, the Cat invites the blue hedgehog to have a go at reeling in a big catch.
After successfully catching Sonic's first fish in Sonic Frontiers, Big the Cat will offer to let players frequently use his rod in exchange for Purple Coins; this offer is followed by a description of Gold Cards. According to the in-game description, Gold Cards are items that can be exchanged for a prize from the list of items presented in Big's shop. These items include Lost Kocos, Memory Tokens, Portal Gears, and even Seeds for upgrading Sonic's stats. While Big's stock does have a limited quantity, the value that players get from participating in fishing is exceptionally worthwhile.
Farming Gold Cards in Sonic Frontiers
Once players understand what Gold Cards are, they will likely be curious about how to obtain them to unlock Big's prizes in Sonic Frontiers. The answer is simple; Sonic can acquire Gold Cards from the same system through which he spends them — Big the Cat's fishing minigame. More specifically, players must spend time fishing in Big's Cyberspace pocket dimension for a chance to catch a rare item known as the Treasure Box. Compared to fish, this chest is a much rarer drop when partaking in the fishing minigame. Nevertheless, once players eventually reel one out of the water, they will be rewarded with one or multiple Gold Cards in Sonic Frontiers.
It should be noted that Gold Card currency in Sonic Frontiers is directly related to Purple Coins. Since Purple Coins are used to "rent" Big's fishing pole, having these coins is crucial for finding new Fishing Holes where Sonic can catch Gold Card Treasure Boxes. While there is no reliable method of getting Purple Coins other than exploration, one of the best ways to farm this minigame voucher currency is through the Starfall event. This event periodically occurs at night in the open world of Sonic Frontiers and triggers a massive meteor shower that drops Star Pieces. Players can collect these pieces to initiate a ive slot machine mechanic that yields Purple Coins. Therefore, if fans ever encounter this event in Sonic Frontiers, they must take advantage of the moment and farm as many coins as they can to fish up Gold Cards with Big.
