Hand keep recommendations. Counts cards in double-up-or-low and provides probabilities. GBF Poker Helper [MOTIVATION] This extension was built out of personal curiosity while exploring the Granblue Fantasy casino and studying GBF poker strategy guides. I couldn't find any tool that could both track drawn cards during Double Up and help evaluate which cards to hold during the main hand phase. The standard Double Up advice — bet Higher on anything below 8, bet Lower on anything above — completely ignores cards already removed from the deck. This extension tracks every card seen throughout a session and recalculates the true probabilities in real time, giving you a meaningful edge as the streak progresses. Version 2.0 goes further, adding a full hand evaluation assistant for the deal phase. [HOW TO USE] Open Chrome Developer Tools (F12), then select the GBF Poker Helper tab from the panel list. The extension activates automatically when you enter a GBF Poker session. - Deal phase — The panel displays your 5 dealt cards and recommends which cards to hold, ranked by Expected Value across all 32 possible hold combinations. - Double Up phase — After each round, the panel shows the real-time probability of drawing Higher, Lower, or Equal based on the cards still remaining in the deck. [FEATURES] - Hold recommendations ranked by Expected Value (EV) for all 32 hold combinations - Supports all hand types: Royal Straight Flush, Five of a Kind, Straight Flush, Four of a Kind, Full House, Flush, Straight, Three of a Kind, Two Pair, One Pair - Joker handled as a full wild card in both evaluation and EV calculation - Real-time Higher / Draw / Lower probability display during Double Up - Full 52-card deck tracking across an entire winning streak - Automatic deck reset on loss, retire, or new deal - Activity log showing each card drawn and deck state [IMPORTANT NOTES] - Probabilities and EV values are purely mathematical and do not guarantee any outcome. - During Double Up, probability differences may be small early in a streak. The more cards that have been drawn, the more accurate and useful the information becomes. - If you have any feedback, comments, or suggestions, feel free to reach out. [DISCLAIMER] This extension operates entirely within the Chrome browser layer. It does not modify, inject, or interact with the game in any way — it only reads network response data to perform mathematical calculations. That said, use it at your own risk, as it may fall under the GBF Terms of Service. [CREDITS] Icons are a subset of images property of Cygames.
