Dublin Venue at a Glance
The Colossus Casino Club operated out of 5 Montague Street, Dublin 2, D02 XE06. It sat a short walk from St Stephen’s Green, Grafton Street and Dublin Castle, basically central Dublin, so you could get there on foot from most city-centre spots rather than calling a taxi.
Two telephone numbers are linked to the club in public listings: +353 1 478 5858 and +353 1 443 3808. Most directories and older pages point to one main domain as the official site: www.colossus.ie.
The operating company on record was Colossus Casino Club Limited, Irish company number 466051. It appears in the registry under NACE code 92.71 - Gambling and Betting Activities. The firm was incorporated on 8 January 2009 and taken off the register on 2 June 2020. A later write-up claims the doors only shut in 2023, suggesting that the venue might have continued under some kind of arrangement after the company itself was dissolved. Public data does not resolve that three-year gap; it is simply left hanging.
Several local business directories describe Colossus as “established over 30 years ago.” If that line is accurate, the club’s roots go back well before the 2009 incorporation, likely under a different legal vehicle or ownership setup. No clear shareholder structure or parent group shows up in accessible corporate records.

Gaming Floor
Colossus was set up mainly as a table-games and poker room rather than a slots hall. Various sources converge on a floor of roughly 14 tables. Some directory pages mention slot machines in passing, but the consistent picture is cards and classic tables as the core product.
Games repeatedly confirmed across different listings and reviews include:
- Blackjack
- Roulette
- Brit Brag (a British three-card brag style game)
- Texas Hold’em poker
- Omaha poker
The poker offer mixed nightly cash games with scheduled tournaments. Both Hold’em and Omaha tournaments are referenced, with timetables historically posted on the club’s own site. No game studio names or software brands are mentioned anywhere, which aligns with the fact that this was a bricks-and-mortar venue only. There is no verified online casino or betting platform tied directly to the Colossus Casino Club brand.
Membership and Hours
Entry worked on a private members’ club model but in a simple way. Membership was free of charge, and there was no need to sign up in advance. New visitors would arrive, show a valid photo ID to confirm they were at least 18, and have their membership processed at the door.
Opening times are harder to pin down. Different kinds of sources report very different schedules, and the gaps are large enough that they probably reflect actual changes over time rather than one shared typo.
| Source Type | Reported Hours |
|---|---|
| Casino directories (LCB, Gambl) | 20:30 - 08:00 |
| Local business directories | 09:00 - 06:00 |
| Irish betting sites | From 20:00 until late |
The evening-through-morning pattern matches what you would expect from a late-night card club. The near-all-day pattern in some local listings is more awkward to interpret. It might point to an earlier operating phase, or to an imported template entry that nobody fully corrected.
For anyone comparing notes between sources: third-party directories for casinos and betting venues often trail real life by years. An entry stamped as updated in 2024 can easily describe how the club ran in 2015. Treat hours in those listings as historical hints, not hard data.
Loyalty Programme and Social Offer
The venue promoted a players’ scheme called Colossus Club. Members could earn points for play and reach defined thresholds where free cash prizes were paid out. Public sources mention the existence of the system and its basic idea but stop short of publishing the details. Exact earn rates, levels, caps and prize amounts never appear in open documentation.
Social activity sat alongside the gaming side. References to the club mention DJ nights on certain evenings, organised packages for groups, and deals that combined gaming with food and drinks. Casino travel write-ups framed it as having something closer to a social club feel than a pure high-end casino, especially when compared with more formal operations in Dublin such as the Sporting Emporium.
Table limits are usually described as accessible rather than high-roller, which fits with the membership concept and the casual tone. In real terms: when planning a first visit to any members’ casino in Dublin, calling ahead to check present-day hours and entry rules is still smart. It takes a couple of minutes and protects you from relying on an old directory listing.
