Sjakkmatt Slot by Relax Gaming

Sjakkmatt is Norwegian for checkmate, and the entire game sits on that one premise. The 5x6 reels are dressed as a polished chess board with alternating light and dark squares, set inside an ornate castle hall with candelabras, columns, and burgundy-and-gold stained-glass windows in the background. Carved chess pieces - king, queen, rook, bishop, knight, pawn - rendered as 3D wood-and-marble icons handle the high pays, with stylised card royals decorated with chess motifs filling the low end. It's atmospheric in a way most 2020 slots aren't bothering with.

The 5x6 grid runs on lines, which already tells you this is from Relax Gaming's older catalogue, before the studio leaned hard into Money Train mechanics and buy bonuses. There is no buy option here. There are no jackpots, no multipliers stacking on the wild, no expanding grid. The wild substitutes for everything except the chess-piece scatters and pays out as a top symbol on its own, which is unusual but not exactly transformative.

Where the game finds its hook is the collection meter sitting next to the reels, shaped like a small green slot for chess pieces. Three captured pieces during base play trigger 8 free spins, and the meter persists between spins, so progress doesn't reset when you stop. The collection runs slowly though, which is the trade-off for a high-volatility 40-line setup.

The bonus is where the chess theme actually does something mechanical. One chess piece walks across the board each spin during the 8 free games, and every square it crosses turns into a wild that stays for that spin's evaluation. So you get a moving wild trail rather than a random scatter of extras, with the path determined by which piece is on the move (a knight's L-shape covers different ground than a rook's straight line). It's a clean idea, even if eight spins is a short window to chase it.

Stacked symbols on the higher tiers help the base game land bigger line hits when the chess pieces themselves stack, but don't expect modern Relax volatility spikes. This is a slower, quieter slot from a studio that has since moved on to louder things. Worth a few sessions for the theme alone if you like board-game settings, less so if you came chasing a max-win number.
