NutsMania is a Twitch-integrated collectible card game built for streamer Beautiful_Nuts' community, "les Noisettes". Viewers become players by spending channel points during live streams to open boosters, with the 3D opening animation displayed as a stream overlay. Cards land in their collection on nutsmania.fr. The game features card collecting across multiple rarities (Common, Rare, Epic, Legendary, Champion), themed album completion, competitive leaderboards (weekly, monthly, yearly, all-time), a cosmetic forge (skins, frames, nicknames), a player-to-player marketplace, daily and weekly quests, achievements, a login streak system, and the "Puits du Destin" random reward feature. The primary in-game currency is poudre de noisette (hazelnut powder). The arena mode features tactical 1v1 duels: each player builds a 20-card deck and battles using the game's signature Noisettes system, where the same currency serves as both health points and the resource spent to deploy cards. Every play leaves you more exposed to direct attacks. Five card types (Garde, Foyer, Sentier, Conseil, Arcane) offer distinct strategies, with synergy bonuses when three of the same type share the field.

Cuttle is an online two-player digital adaptation of the classic card game (by the same name) played with a standard 52-card deck of cards. This version uses minor tweaks to the rules of the traditional game in order to fine-tune the game's balance for competitive play. The original card game, which dates back to at least the 1970s, is widely regarded as one of the earliest examples of a combat-focused card game. Its use of direct player interaction, permanent cards, and tactical resource management predates and foreshadows mechanics later popularized by collectible and trading card games such as Magic: The Gathering. By bringing Cuttle to a digital platform, this online version preserves the depth and elegance of the original design while making one of the foundational games of the genre accessible to a modern audience.
