Norwegian-themed chess slot from Relax Gaming. 5×6, 40 lines, with collected pieces unlocking free spins where one piece walks the board leaving Wild trails.
Sjakkmatt is Norwegian for checkmate, and Relax Gaming leans hard into the theme. The 5×6 grid sits inside what looks like a stately Norwegian castle hall, with polished light-and-dark squares forming the playing field, ornate columns flanking the reels, candelabras flickering in the corners, and burgundy-and-gold stained-glass windows behind it all. Carved King, Queen, Rook, Bishop, Knight and Pawn icons rendered in 3D wood and marble do the heavy lifting on the paytable, while the card royals get tarted up with little chess motifs so they don't feel completely out of place.
Mechanically this is older Relax catalog, released July 9, 2020, well before the studio's Money Train era reshaped what people expect from them. You get 40 paylines, RTP of 96.09%, high volatility, and a bet range of 0.05 to 200 EUR. There's no Buy Bonus button, no jackpot ladder, no stacking wild multipliers, no expanding grid. Just a clean base game with stacked higher-tier symbols and a single bonus round to chase.
The unusual touch sits at the top of the paytable. The Wild substitutes for everything except the chess-piece scatters, and it also pays as a top symbol in its own right. Wild and the H1 chess piece both pay 5x line bet for three of a kind; Wild caps at 15x for five, H1 at 10x. It's a quirk you don't see often, though honestly it doesn't change how the game feels minute-to-minute. You're still hunting the same combos.
Free Spins are where Sjakkmatt earns its name. Chess piece scatters drop in the base game and get banked on a meter that persists between spins, so progress carries over. Three collected pieces triggers 8 free spins, and during the bonus a single chess piece walks across the board each spin, leaving Wilds in its trail. The path depends on which piece is moving. A Knight's L-shape covers very different territory than a Rook's straight line, which keeps the bonus visually interesting even if the math is straightforward.
Honest gripes? The collection meter is slow. Really slow. You can grind for ages before triggering the round, and when you finally do, 8 spins isn't a lot of runway. There's also no formal max win cap on this older Relax engine, which sounds generous but in practice the volatility ceiling feels modest by 2026 standards. It's a handsome, themed slot with one neat bonus idea, not a modern hit-chaser.
