How Long Does Diablo: Unbound Take to Play? Per Level, Per Act, Per Campaign
A three-act Diablo: Unbound campaign runs 9 to 13.5 hours, or about 11.25 hours at 75 minutes per dungeon level. Formula, calculator and full table included.
Last updated:
A full three-act campaign of Diablo: Unbound takes 9 to 13.5 hours. At a standard pace of 75 minutes per dungeon level it lands at 11.25 hours — about six sessions of 90 minutes. A single level is 60–90 minutes, and one act is 3–4.5 hours. Those last two figures are the publisher's; the campaign number is our multiplication of them.
Short answer, then the working
The publisher gave two time ranges and nothing else. Everything below is arithmetic on those two numbers, which is why this page can show its working instead of asserting a figure.

| Question | Answer | Source |
|---|---|---|
| How long is one dungeon level? | 60–90 minutes | Publisher (Confirmed) |
| How long is one act? | 3–4.5 hours | Publisher (Confirmed) |
| How long is the full campaign? | 9–13.5 hours | Our calculation (9 levels × the level range) |
| How many sessions is that? | 5–9 sessions of 90 minutes | Our calculation |
The two published figures are internally consistent: three levels at 60 minutes is 3 hours, three at 90 minutes is 4.5 hours. That consistency is the only reason the multiplication is safe. If the publisher had said "about an hour per level, about five hours per act", the extra time would be act overhead we could not see, and multiplying would be wrong.
Use the calculator
Run time calculator
Same arithmetic as the table below, with the two published inputs exposed.
9 dungeon levels — three per act, confirmed by the publisher.
11.25 hours
9 levels × 75 minutes = 675 minutes. That is 6 sessions of about two hours, or 8 sessions of 90 minutes.
Play time only. Setup, teardown and rules lookups are not included, and the publisher has not published a setup time.
The formula and the assumptions behind it
The formula is deliberately small:
total minutes = acts * 3 levels per act * minutes per level
total hours = total minutes ÷ 60
Two of those three inputs are published: acts (3) and levels per act (3). The third — minutes per level — is published as a range, not a point, so this page lets you pick where in the range your table sits.
Assumptions, stated so they can be attacked:
- Every level takes the same time. In practice a first level with rules-teaching runs long and a final boss level runs longer. The range absorbs some of that; a real campaign will not be uniform.
- A campaign is exactly nine levels. Three acts of three levels is confirmed. Whether Torment adds more play is a separate question and is not counted here.
- Play time only. Setup, teardown, card shuffling and rules lookups are not in the published figures and are not in this table. For a miniatures game on hex tiles, that is tens of minutes per session.
- Player count does not change per-level time. This is the weakest assumption, and it is not ours by choice — the publisher has not said whether monster counts or health scale with player count. If they do, a solo campaign may run shorter or longer than a four-player one.
- First session includes teaching. We have not added a teaching allowance, because there is nothing to teach ourselves from: the rulebook is unpublished.
Result table for every combination
Nine levels at three paces, plus single-level rows for session planning. Values are play time only.
| Pace | Acts | Levels | Total minutes | Total hours | 90-min sessions |
|---|---|---|---|---|---|
| 60 min/level | 0 (one level) | 1 | 60 | 1 | 1 |
| 60 min/level | 1 | 3 | 180 | 3 | 2 |
| 60 min/level | 2 | 6 | 360 | 6 | 4 |
| 60 min/level | 3 | 9 | 540 | 9 | 6 |
| 75 min/level | 0 (one level) | 1 | 75 | 1.25 | 1 |
| 75 min/level | 1 | 3 | 225 | 3.75 | 3 |
| 75 min/level | 2 | 6 | 450 | 7.5 | 5 |
| 75 min/level | 3 | 9 | 675 | 11.25 | 8 |
| 90 min/level | 0 (one level) | 1 | 90 | 1.5 | 1 |
| 90 min/level | 1 | 3 | 270 | 4.5 | 3 |
| 90 min/level | 2 | 6 | 540 | 9 | 6 |
| 90 min/level | 3 | 9 | 810 | 13.5 | 9 |
Read the table two ways. Planning a single evening: the one-level rows tell you whether a level fits before someone has to leave. Planning a campaign: the three-act rows tell you how many weeks you are committing to at your group's pace.
The 75-minute rows are the ones we would use for budgeting, because 75 minutes is the midpoint of the published range and produces the 11.25-hour campaign figure quoted at the top of this page.
Where these numbers stop being reliable
Four situations break the arithmetic.
If your group is slow, the ceiling moves. 90 minutes per level is the publisher's ceiling, but a four-player table with analysis paralysis can exceed a published range. The table cannot model that, and no table can.
If player count scales the game, solo is unknown. A solo campaign might be faster per level or slower, depending on whether the game reduces monster counts or expects you to run multiple characters. The solo page tracks what is and is not known.
If setup is heavy, session count is optimistic. Eight 90-minute sessions of play time could be ten sessions of real calendar time once setup and teardown are counted. The publisher has not stated a setup time, so we have not invented one.
If the campaign slips, none of this changes — but your plans might. The release is "2027" with no date, and the Gamefound campaign opens in Q1 2027. Playtime is a design property and is unlikely to move; the schedule around it very much can, and the availability section is where that is tracked.
Frequently asked questions
How long does Diablo: Unbound take to finish?
Nine levels of 60–90 minutes each, which works out to 9–13.5 hours for a full three-act campaign. That figure is our multiplication of the publisher's per-level range; the publisher has confirmed 60–90 minutes per level and 3–4.5 hours per act, but has not published a campaign total.
How long is one session of Diablo: Unbound?
One dungeon level, at 60–90 minutes, is the natural session unit. A full act is 3–4.5 hours, which the publisher says can be played in one sitting or split using the save system. There is no published setup time, so add that to whatever you budget.
Is the 11.25 hour figure official?
No. It is nine levels at 75 minutes, the midpoint of the published range. Official figures are 60–90 minutes per level and 3–4.5 hours per act; the campaign total and the session counts on this page are labelled as our calculation wherever they appear.
How long does a single act of Diablo Unbound take to complete?
