Electron desktop companion combining League of Legends live stats via the LCU API with a 10-game mini-casino coin economy
miniGamba is a two-mode desktop app with a full dashboard and an always-on-top overlay. The dashboard provides LoL summoner lookup, live in-game scoreboard (KDA, CS, gold, objectives), and champion-select detection powered by the League Client Update (LCU) API and the Live Client Data API. The overlay adds a 10-game mini-casino (slots, blackjack, coin flip, minesweeper, scratch cards, higher-or-lower, wheel, derby, dice, poker) with a coin economy driven by in-game events, daily tasks, hourly bonuses, and passive activity detection.
