Very Hot 40 Respin, from Fazi, uses a 5-3 reel configuration with 40 paylines and medium volatility. The game offers a 96% RTP and a top-win of 42x the stake. Core mechanics include a Respin Wild that can trigger an additional re-spin, Scatter symbols, and an expanding wild that fills spaces on the reels; these are supported by a Risk/Gamble (Double) feature intended to potentially increase winnings on selected outcomes.

Respin Wild is a wild symbol that remains on screen to grant another spin, increasing opportunities for line wins. Expanding wild with re-spin refers to a wild that grows to cover more positions and can initiate an extra spin.

Betting range runs from 0.2 USD to 500 USD. The game features themes including Cherry, Star, Grapes, Bell, Watermelon, Red, Classic style, Fruit, Plum, and Lemon.
