Cocktail Beach | Construct 3 | HTML5 Game with Node.js Backend

Cocktail Beach is an HTML5 slot machine game made in Construct 3, shipped together with an optional Node.js + MongoDB backend for server-side game logic. It is a 5-reel, 3-row video slot with 20 paylines, scatter-triggered free spins, cascading (drop) symbols and Big Win / Mega Win / Super Mega Win celebrations.

Out of the box the game runs 100% in the browser – just upload and play. When you are ready for server-authoritative gameplay, the included backend moves spins, balances, RTP control and history onto your own server with persistent MongoDB storage.
