If you finished Box One, the puzzle box presented by Neil Patrick Harris, and wanted another evening like it, the right answer depends on which part you liked. Box Two is the obvious next stop if you want more from the same designers. Our games are built for the reader who wanted the same feel over a longer night. EXIT is the budget way to keep going, and PostCurious makes the most beautiful thing in the category. Below is how long each one runs and who it suits.
We make some of the games below, so read us with that in mind. Both of us have played Box One. Playtimes come from each company's own product page except where a retailer is named, and every game links out so you can check us.
The most common complaint about Box One is the useful one
Box One is very good. It holds 4.7 out of 5 across 642 Amazon ratings and 4.9 at Target, and theory11's own review page runs about 4.87, though that one is first-party and moderated so treat it as the softest of the three.
The criticism that recurs more than any other, and it appears even inside theory11's own moderated reviews, is that it ends too soon and asks too little. One buyer there wrote that the game "held my hand 90 percent of the time." Room Escape Artist, who gave it a Golden Lock award and rated it highly, still concluded plainly that it was not challenging.
So this is not a weak product that needs replacing. It is a very good one that a lot of people finished faster than they wanted to, and that single fact is what should drive whatever you buy next.
Box One vs Box Two, and which to play next
Box Two is the direct sequel and the obvious first place to look. It runs longer, around two to three hours by Room Escape Artist's reckoning, it is built for 1 to 2 players and rated 14 and up, it drops Box One's forced 24-hour pause, and it adds an online chat interface that pairs you with other players in real time. Nothing gets destroyed and it resets the same way.
Two things temper it. It divides people much more than Box One did, holding 3.8 out of 5 at Target against Box One's 4.9. And Room Escape Artist's verdict was that Box Two is not another Box One, which is the point: it is a different experience from the same studio rather than a second helping of the one you enjoyed. The two work in either order.
Box One itself came out in October 2020 and is still in print, rated 14 and up, designed for a single player though a pair works fine.
Puzzling Pursuits, for the same feel over a longer night
We make story-led at-home escape room games where the obstacle between you and the ending is usually a cipher, a hidden pattern or a piece of lateral thinking. Most of our boxes hold two parts that resolve one story, which is where the length comes from. Like Box One, nothing needs cutting or writing on, so a finished game passes to a friend intact.
On length, concretely: Box One is reported at roughly 45 minutes to two hours of active play. Our two-part games run two to four hours and more. If the problem was that it ended too soon, that gap is the whole point.
What comes in one Blackbrim: 1876 box. The volume of material is where the extra hours come from.
Both of us played Box One before writing this, which is what the rest of this section rests on. theory11 publishes no difficulty rating, so this is our judgement rather than a measured scale, but having done both: Blackbrim sits a little above Box One, and Down the Rabbit Hole sits below it.
- Blackbrim: 1876, our Victorian detective game is the one to take if you liked Box One and wanted more of it. You play a private detective chasing a criminal who has taken a town's police force hostage. 1 to 6 players, 2 to 4+ hours across two parts, ages 14+, 4.8 stars from 525 reviews.
- Down the Rabbit Hole, our Wonderland escape game is the one to take if Box One was already at the edge of what your table enjoys, or if you want a lighter evening. It is gentler than Box One rather than a step up. 1 to 6 players, 1.5 to 3+ hours, ages 12+, 4.8 stars from 77 reviews.
If Box One left you wanting a longer night, see how Blackbrim: 1876 works. It carries 4.8 stars from 525 reviews.
Some of the puzzles, especially in part 2, were a little more challenging than other mystery games that we've played. There was just less hand-holding and explicit direction for how the puzzles work, so we really had to think creatively to make our way through the game.

We rate Blackbrim 14+, and it is the harder end of what we make.
Why us rather than Box Two
Box Two also solves the length problem, so it is worth being direct about where we differ.
Box Two is a different experience from the studio you liked, by the reviewers' own account and by ours. Our games are more of the thing Box One did well: a story you work through with physical materials and no hand-holding. Box Two's multiplayer pairs you with strangers online, while ours seat 1 to 6 people around your own table working the same materials, which is a different evening entirely. And on the numbers, Blackbrim carries 4.8 stars from 525 reviews against Box Two's 3.8 at Target.
Blackbrim asks more of an evening than either of them, and what you get for it is roughly double Box One's play. Down the Rabbit Hole sits nearer Box One's length and is the gentler of our two.
Where Box Two genuinely wins: if what you loved about Box One was the magic-trick craft of the object itself, the way the box does things you did not expect, nobody on this list including us does that the way theory11 does. Buy Box Two for that and enjoy it.
If your actual complaint was that one good evening was not enough, the three-game Blackbrim Trilogy runs 10+ hours across six parts and carries 4.9 stars from 533 reviews. You can also browse the full range of our at-home escape room games to compare lengths before choosing.
EXIT: The Game, the budget way to keep going
EXIT from Thames & Kosmos is the budget option, and the catalog runs past fifty titles so you will not run out. Standard boxes take 1 to 4 players, 1 to 2 hours, ages 10 or 12 and up depending on the title, with a difficulty rating printed out of 5.
The trade-off matters more here than usual, given what you just came from. EXIT's standard boxes are consumed as you play. The manual expects you to fold, write on and cut up the components, and suggests tearing them by hand if you have no scissors. Everything Box One does with resetting and passing along, the standard EXIT line deliberately does not do. Their separate Kids line, for ages 5 to 7, is replayable.
PostCurious, if you want something long and beautiful
PostCurious makes the most striking objects in this category, which is the closest anyone comes to Box One's production values. These are long puzzle adventures with tarot decks, fabric maps and watercolor artwork, sold through AllPlay. The Light in the Mist runs around five hours; The Emerald Flame is longer again. Built for 1 to 4 players, ages 14 and up.
The stories here are atmosphere more than plot, so take this as a recommendation for the puzzle craft above all.
If it was the mystery you liked
Box One is not really a whodunit, but plenty of people arrive at it from that direction. If solving a crime is what you want next, Deadbolt Mystery Society runs 2 to 3 hours of murder-mystery deduction a box, and Unsolved Case Files does single cold cases that scale to a whole party.
We compared that whole category in our guide to games like Hunt A Killer, which covers eight of them on format and length.

Common questions
These are the questions we see asked most by people who have just finished Box One.
How long does Box One take?
Reported playtimes cluster between 45 minutes and two hours of active play. It still spans two days, because the game contains a deliberate 24-hour pause partway through that you are not meant to skip. At least one page currently ranking for Box One claims you can pause and resume whenever you like, which is wrong.
Can you play Box One more than once?
Not meaningfully. Nothing gets destroyed and theory11 publishes a reset video so you can pass it on, which is genuinely unusual and one of the best things about it. The game is the same every time though, so the surprises only land once. Take care with the supplied pen, since writing on the cards is the common way a reset gets spoiled.
Do you need internet to play Box One?
Yes, throughout, on a phone or laptop. The packaging does not make this obvious and buyers have said so in reviews. Our games use an online companion guide for hints and answer checking in the same way.
Should I play Box One or Box Two first?
Either order works, since the stories are independent. If you have played neither, Box One reviews far better at retail, so most people should start there.
Is Box One good for a family?
It is rated 14 and up and built for a single player, so it is a poor fit for a family evening. For a table with mixed ages, our Down the Rabbit Hole is rated 12+ and plays 1 to 6.
How long an evening should I expect from each of these?
Box One runs 45 minutes to two hours, Box Two two to three, and a standard EXIT box one to two. Our two-part games run two to four hours and more, and the Blackbrim Trilogy runs 10+ across six parts. PostCurious sits at the long end, with The Light in the Mist around five hours. As a rule in this category, a shorter box means a shorter evening rather than a worse game.
Playtimes and availability were checked in August 2026 and will drift over time.
