The Crime File

The Crime File is a high-volatility, 5×4 detective-themed slot from Hacksaw Gaming, built around expanding multiplier wilds and stacked high-value symbols that steadily fill a total multiplier bar as the investigation unfolds across each spin.

Theme and gameplay feel

The setting is a dark, gothic detective world — shadowy libraries, looming castles, and noir-styled characters give The Crime File a moodier, more atmospheric feel than a typical bright slot theme. Wild symbols substitute for regular pays and expand upward whenever they form part of a winning combination, revealing a multiplier that gets added to the game's running total when they do. High-value symbols can also stack and merge into full-height columns, awarding extra multipliers even when they're not directly part of a winning line, which keeps the multiplier bar climbing steadily through a session.

What the RTP means for you

At 96.33%, The Crime File sits above the typical industry midpoint, which is a good sign for long-run player value. Over a large enough number of spins, that figure translates into a fairly generous share of wagered stakes being returned compared with much of the wider slot market.

Volatility explained

This is a high-volatility game, and the mechanics back that up: the free spins round offers three trigger tiers (10, 15, or 20 spins depending on how many scatter symbols land), with wilds expanding to full height throughout and multipliers stacking anywhere from 2x up to a hefty 100x. There's no retriggering once inside the bonus, so the round is a single, self-contained shot at building that multiplier total as high as possible.

Max win potential and stakes

The Crime File offers a maximum win of 10,000 times the stake, a strong ceiling that reflects how quickly those expanding-wild multipliers can compound. Stakes run from 0.10 up to 100 per spin. For players wanting more control over how they enter a bonus round, feature buy options include a direct route into the free spins, a higher-volatility persistent-wild variant, and boosted-odds spins that guarantee extra expanding wilds.

Verdict

The Crime File combines a genuinely atmospheric detective theme with a well above-average 96.33% RTP and a multiplier system that rewards patience through the base game. High volatility means it's built for players comfortable with quieter stretches in exchange for the chance at that 10,000x ceiling.
