Blocks is a title from Hacksaw Gaming. Presentation-wise it's wrapped in polished, characterful visuals, and it leans toward a medium high volatility profile at 93.77% RTP. Under the hood you'll find 5 reels and 25 paylines.
The medium high volatility strikes a middle ground that should suit most playing styles. On balance, Blocks is a dependable option worth a few spins in the demo first.
The RTP of 93.77% is below the industry average of ~96%. This is common for older slots or those with special features. The lower RTP may be offset by unique mechanics or higher maximum win potential.
Medium-high volatility means wins come less frequently but tend to be larger when they hit. Players should be prepared for dry spells between bigger wins, requiring a moderate bankroll.
About 1 in 3 spins results in a win. This is a moderate hit frequency that balances win frequency with payout size.
3.0 / 5 — Good
