What Is Cash of Kingdoms?
Cash of Kingdoms by Microgaming is a 2018 medieval fantasy slot featuring the Invading Wilds mechanic — a system where Wild symbols march across the reels over successive spins like armies invading territory. The game operates on a 15-payline grid where Wild symbols that land on the reels advance one position to the left on each subsequent spin until they fall off the grid.
The Invading Wilds mechanic creates a persistent base-game engagement layer that extends across multiple spins. When a Wild lands on reel five, it has a potential five-spin journey across all five reels before exiting. If multiple Wilds are progressing simultaneously from different entry points, they can overlap to create extensive multi-reel coverage.
RTP & Volatility
Cash of Kingdoms carries a published RTP of 96.86%. High volatility means wins are less frequent but can be significantly larger, rewarding patience.

Key Features
Each Invading Wild entered on reel five marches left by one position on each subsequent spin. On reel four it covers one position; on reel three it covers three positions (the full three rows of that reel); on reel two it covers three positions; on reel one it covers three positions, then exits. The expanding coverage as it moves through the central reels is the mechanic's key characteristic.
Scatter symbols trigger the free-spins round when three or more land anywhere on the reels. During free spins, the Invading Wilds mechanic accelerates — Wilds enter more frequently and their progression continues throughout the bonus. The combination of multiple simultaneously progressing Wilds during free spins on a 15-payline grid is what drives the high win potential.
The Siege Wilds feature can randomly trigger during the base game, placing a large Invading Wild army directly onto the reels — skipping the reel-five entry requirement and immediately advancing the multi-reel coverage.
Theme & Design
A medieval siege warfare setting: armoured knights, siege engines, castle battlements, trebuchets, swords and shields, and heraldic banners across the 15-payline grid. The colour palette is stone grey, deep reds and battle-worn greens. The marching army Wild animations are visually distinctive.
Verdict
Cash of Kingdoms is a distinctive Microgaming slot that earns its place through the genuinely unique Invading Wilds mechanic. The 96.86% RTP is excellent for high-volatility, the persistent Wild progression creates multi-spin engagement sessions, and the medieval siege theme is executed with clarity. For Irish players who enjoy mechanics-first slot design, it is recommended.
