Teorema Rooms in Sofia, Bulgaria

Teorema Rooms is an active Sofia escape-room operator with three current games split between two central addresses: Atlantis and TNT at 11 Krakra Street, and The Lost Ark at 28 Damyan Gruev Street. It is a booking-based experience for small groups rather than a walk-in attraction, and the choice of game matters because the themes, team sizes and playing times differ substantially. Travellers who enjoy puzzles, collaborative challenges and designed narrative environments will get the most from it. The main limitation is that the brand no longer corresponds to one single doorway, so confirm both your game and its address before setting out.

The current Teorema website presents the rooms as original, independently created experiences rather than a franchise. TNT was the company’s first project, followed by Atlantis and, in 2026, The Lost Ark. The games are designed around sets, mechanisms and puzzles rather than padlock-heavy sequences. That makes the operator useful for both first-time players and people who have already tried escape rooms elsewhere, although the experience is still dependent on teamwork, communication and comfort in enclosed themed spaces.

TNT is the shortest of the three current rooms. It is a bank-heist action-comedy scenario for two to seven players with 60 minutes of game time. The official page labels it for Bulgarian and English play, describes multiple spaces, logic riddles and mechanical puzzles, and states that there is no actor and that the game is not intended as horror. Players with severe claustrophobia are specifically asked to contact the team before booking. The page recommends teams of three to five, though smaller and larger groups within the published two-to-seven range can participate.

Atlantis is also at Krakra 11. It takes two to seven players and lasts 75 minutes, using an adventure theme centred on Poseidon and a lost city. The official material again warns that there are dark and enclosed spaces even though the game is not presented as horror. The Lost Ark, at Damyan Gruev 28, is the longest current escape-room option: the main Teorema page lists four to eight players and 120 minutes. Groups should therefore choose based not only on story preference but also on available time, headcount and sensitivity to confined or dark environments.

Pricing is game-specific and can change, so the booking system should be treated as the final authority. At the time of this research, the official site lists TNT from €23 per person and Atlantis from €25, while The Lost Ark is shown from €60 on the main page. TNT’s detailed page also states that prices are per player, that a €25 reservation deposit is non-refundable and that an animator charge applies to players under 14. Those details should be rechecked when booking because group size and product rules affect the final amount. Do not plan around old prices from archived travel listings.

Both locations publish the same current opening window, Monday through Sunday from 10:00 to 22:00. Those are venue hours, not a guarantee that you can start a game at any moment. Escape rooms operate by reserved time slot, and popular evening or weekend sessions can fill. Arrive according to the instructions in your confirmation rather than treating 22:00 as a walk-in closing time. The official contact number and email are shared across both addresses, which is useful if your group is delayed or uncertain about the correct location.

The Krakra 11 branch is near Sofia University and the Doctors’ Monument, and Teorema’s current site says metro and other public-transport stops are only a short walk away. The operator also notes blue-zone street parking and paid parking at San Stefano Plaza. Damyan Gruev 28 hosts The Lost Ark and additional event space. Because the two addresses are separated across central Sofia, typing only “Teorema Rooms” into navigation without checking the booking can create an avoidable last-minute transfer. Use the exact branch shown for your game.

Language support is important for travellers. TNT is explicitly marked BG / EN, and Teorema maintains an English-language booking site. If your team needs English throughout the full experience, confirm that requirement for the specific room when reserving rather than assuming identical language handling across every format. Children also have game-specific rules. TNT states that players under 14 require an animator and that children under seven are not charged but may participate only with two adults. Families should verify current age and supervision rules for the room they choose.

Accessibility cannot be summarised with a simple yes or no from the current public contact page. The operator lists accessibility among its frequently asked questions but does not publish enough detail there to confirm step-free routes, doorway widths or suitability for particular mobility needs. Escape rooms can also involve darkness, confined spaces and physical movement even when they are not horror experiences. Contact the team before paying if anyone in your group has mobility limitations, severe claustrophobia, pregnancy-related concerns or another condition that could be affected by the game environment.

Allow more time than the advertised game clock. TNT itself lasts 60 minutes, Atlantis 75 and The Lost Ark 120, but you also need arrival, briefing and the post-game transition. A sensible overall block is roughly 90 minutes for TNT or Atlantis and at least two and a half hours for The Lost Ark, while following the venue’s own arrival instructions. Teorema Rooms works best when the practical pieces are fixed in advance: select the game for your group size, book the correct branch, confirm language or access needs and arrive on time. Do that, and the experience can become a distinctive indoor counterpoint to a day of conventional sightseeing in Sofia.
