Case Files by Kiwii Slot Overview
Case Files by Kiwii sets its detective investigation against a dark blue cityscape, with neon signs and gold-framed reels. Its cascading reels share a mechanic with The Crypt 2, while Case Files presents winning symbols as clues bagged during an investigation.
Mystery Evidence turns every sealed bag on the board into the same symbol, while Cold Case free spins build a persistent Evidence multiplier after each tumble. High volatility accompanies a maximum win of 5,000x the bet. Explore these features in the free demo on BonusTiime.

Case Files Slot Features

Mystery Evidence, Cold Case free spins, and the Agent Noir 2x detective bonus shape the core action, with sealed bags, tumble chains and a multiplier that grows after every tumble. The bonus menu adds three paid options: Hot Lead, which stays on and is charged on every spin, and two one-time buys that open Cold Case.
Mystery Evidence
Sealed evidence bags can land on any reel in the base game and in free spins. Before the board is paid, every bag opens into the same symbol, either a regular clue or the detective badge wild, and bags that drop in during a tumble open the same way. The detective badge wild lands on reels 2 to 6 and substitutes for any paying symbol.
Cold Case
Cold Case starts with 4 or more Case Closed folders landing anywhere when the base-game tumbles end. It awards 12 free spins, plus 2 more for each folder beyond 4. Folders pay nothing themselves and are never removed by a tumble.
Free Spins
Free spins tumble like the base game, but every win receives the Evidence multiplier. That multiplier rises by 1 after each tumble and never resets during the feature. If 3 or more folders land when a free spin tumble ends, the game adds 5 free spins, up to 60 total. The Agent Noir 2x detective bonus, which doubles the entire base win on some rounds whose total base win is 1x to 11x, does not apply to rounds with free spins.
Hot Lead
Hot Lead is a paid per-spin option that increases the frequency of Cold Case rather than opening free spins directly. It stays active until you turn it off. The bonus menu holds three paid options: Hot Lead, charged on every spin, and two one-time buys that open Cold Case.
- Hot Lead: x1.25 the bet per spin; Cold Case then triggers about 1 in 162 spins instead of about 1 in 240.
- Open Cold Case: x100 the bet; opens Cold Case with 12 free spins and Evidence at x1.
- Prime Suspect: x150 the bet; opens Cold Case with 12 free spins and Evidence at x3.

Case Files Slot Review
Case Files builds its identity around a noir investigation, with neon city backdrops, dossier styling, and clue cards laid out like evidence photographs. The detective badge wild and sealed bags keep the theme tied to the mechanics, so the presentation supports the fiction instead of sitting on top of it.
The strongest idea is Mystery Evidence, because sealed bags can turn into the same symbol before a board is paid. That adds uncertainty to each tumble, while High volatility keeps the action uneven. The base game and bonus both rely on the same cascade structure, so the slot leans more on timing than variety.
In Cold Case, every win receives the Evidence multiplier, which rises after each tumble and never resets during the feature. The 96.49% RTP is respectable, but the package still feels more practical than standout.

Case Files Slot FAQ
How Does Cold Case Trigger?
Cold Case starts when 4 or more Case Closed folders land anywhere on the reels as the base game tumbles end. It then opens 12 free spins, plus 2 more for each folder beyond 4. The folders pay nothing themselves and are never removed by a tumble.
What Does Hot Lead Cost And Do?
Hot Lead costs x1.25 the bet per spin. It raises the chance of opening Cold Case to about 1 in 162 spins instead of about 1 in 240. The option stays active until you switch it off, so it changes the game during normal play.
What Are The Other Buy Options?
Open Cold Case costs x100 the bet and opens Cold Case directly with 12 free spins at Evidence x1. Prime Suspect costs x150 the bet and also opens Cold Case directly, but the Evidence multiplier starts at x3. Both options buy the free spins feature outright.
What Is The Maximum Win?
Case Files has a maximum win of 5,000x the bet. The game ends the round as soon as that cap is reached, so no result can go beyond it. That figure gives the slot a clear top end, even with its high volatility and tumble based structure.
Can You Play A Free Demo, And How Does Mystery Evidence Work?
Yes, BonusTiime offers a free demo with no deposit or account needed. Mystery Evidence lets sealed bags land on any reel in the base game and free spins. Before payout, each bag opens into the same symbol, either a regular clue or the detective badge wild.
