4 Corners of Rome

4 Corners of Rome is a 5x5 online video slot from Microgaming, built around 40 win lines and a return to player of 96.05%. The game supports stakes from 10p to £30, with a default stake level of £2 and a maximum win of 6,300x the bet.

The main feature is Lock and Load, which activates when matching symbols land on diagonally opposite corners. When triggered, selected symbols can hold through re-spins, other visible wins may also stay in place, and intersecting locking lines can upgrade symbols to Wilds. The slot also includes a Buy a Bonus option with a gamble feature, allowing players to attempt entry to the Free Spins round directly.

Free Spins can be triggered by landing 3 bonus symbols, with three selectable modes: 3, 6, or 9 spins. Each mode changes volatility and corner Wild behaviour, while a fully locked reel during the feature awards extra spins. The demo version lets players play for free and practice before playing for real money.
