Dr. Hollow’s Hours Slot Specifications

Dr. Hollow’s Hours uses 6 reels with 2 to 7 rows per reel, expanding up to 9 with Incision, and Ways to win, so matching symbols pay across adjacent reels from the left. The house edge sits at 3.80%, and a win needs the same symbol, or a Scalpel Wild, on at least 3 adjacent reels from reel 1, with the cut reels giving 64 to 321,489 ways. Winning symbols are wiped away as chalk outlines in a Clean-Up, the symbols above drop down and new ones fall in, and Clean-Ups continue while new wins form.

Dr. Hollow’s Hours Slot Features

Scalpel Wild, Incision, Patient, Pocket Watch, Red Ledger, Ward Rounds, Night Rounds, Lights Out, and The Witching Hour give Dr. Hollow’s Hours a layered structure, with reel expansion, collection, and bonus progression all feeding into the same hospital-themed math.

Scalpel Wild

Scalpel Wild lands on reels 2, 3, 4 and 5 only and substitutes for every regular symbol. When it lands, Incision cuts its own reel again and adds 1 or 2 rows under the Wild, up to 9 rows, before wins are counted. Several Wilds on one reel add their rows together, still up to 9. A Wild that drops in during a Clean-Up substitutes but does not cut.

Patient

Patient symbols carry hidden wristband values from +1 and up. The game reveals them at the end of Ward Rounds or when a room fills, then adds them to the Global Multiplier. Collected Patients also appear in every bonus, and the values range from +1 to +50, or +2 to +100 in The Witching Hour.

Pocket Watch

Pocket Watch symbols start the bonus flow and can land once per reel. They trigger Night Rounds with 3, Lights Out with 4, or The Witching Hour with 5 or 6. Inside a bonus, 2 Pocket Watches add 2 spins and 3 or more add 4 spins, and The Witching Hour allows at most one retrigger.

Red Ledger

Red Ledger lands on reel 6 only and appears rarely. With 3 or more Pocket Watches it upgrades the bonus by one hour: 3 Pocket Watches plus the Red Ledger start Lights Out, and 4 plus the Red Ledger start The Witching Hour.

Ward Rounds

Ward Rounds starts when 3 or more Patients land in one spin, including Patients from Clean-Up. The grid dims, the Patients lock, and every other position respins for 3 respins. Each new Patient resets the count to 3. Respin wins go into the Treatment Total, then every wristband is revealed and added to the Global Multiplier, which starts at ×0 here, and the win is Treatment Total × Global Multiplier. If the Treatment Total is 0, the Patients pay their combined wristband total × 0.5 the bet.

Night Rounds

Night Rounds begins with 3 Pocket Watches or through its direct bonus buy. The Ward panel stays active for the whole bonus, Patients appear twice as often as in the base game, and wristbands keep feeding the Global Multiplier. It also grants 10 spins. The Ward panel holds 12 beds in 4 rooms of 3: each room that fills reveals its 3 wristbands into the Global Multiplier, which starts at ×1 and never resets during the bonus, and filling all 12 beds adds 3 spins and doubles the Global Multiplier once.

Lights Out

Lights Out adds the Evidence Board to the Ward panel and starts with 4 Pocket Watches, or 3 Pocket Watches plus the Red Ledger. It runs for 10 spins and every reel has at least 4 rows. At the start of every bonus spin, 1 to 3 Evidence Pins are pushed into random positions, each starting at ×2 and, in Lights Out, only in the top 4 rows. Pins in the same row or diagonally adjacent are joined by red string into a case, and a win passing through any pin of that case is multiplied by the sum of its pin values, after which every pin of the case goes up by +1. Pins stay for the whole bonus, up to 12 on the grid.

The Witching Hour

The Witching Hour fixes all reels at 7 rows and guarantees a Scalpel Wild on every spin. It combines the Ward panel and an Evidence Board that covers all 7 rows, doubles wristband values, and runs for 8 spins. The Hour Strikes also doubles the Global Multiplier on the last spin, adding a final lift to the bonus.

Bonus Buy

Bonus Buy holds four one-time buys that start a bonus straight away, plus two per-spin modes that stay on until you change them.

• Ward Rounds: x60 the bet; starts directly in Ward Rounds with 3 Patients admitted.
• Night Rounds: x100 the bet; starts directly in Night Rounds.
• Lights Out: x250 the bet; starts directly in Lights Out.
• The Witching Hour: x600 the bet; starts directly in The Witching Hour.
• Night Shift: x1.5 the bet per spin; more Pocket Watches, and bonuses trigger about 2.7x as often.
• Full Moon: x3 the bet per spin; guarantees a Scalpel Wild on every spin and brings more than twice as many Patients.

Dr. Hollow’s Hours Slot Review

Dr. Hollow’s Hours builds its identity from a hospital horror frame, parchment menus and a dim ward setting that fits the medical jargon on the reels. The clinical styling gives the game a clear visual lane, and the paperwork look matches the bonus structure rather than feeling pasted on.

The main draw sits in the Scalpel Wild and the reel expansion it triggers through Incision, because that changes the board before wins are counted. High volatility and a 15,000x cap keep the action sharp, but the buy menu and mode ladder make the structure feel very deliberately engineered.

Dr. Hollow’s Hours builds progression within individual bonuses: Pocket Watches can add spins, Patients increase the Global Multiplier, and Evidence Pins remain for the whole bonus.
