How Long Does It Take to Complete Undertale is a question many players ask before diving into Toby Fox’s beloved RPG. Whether you’re a newcomer deciding when to start, a speedrunner planning a challenge, or a completionist gathering goals, understanding likely playtimes helps set expectations and keep the experience fun.
In this article you’ll learn rough playtime ranges for different routes, what changes the clock, platform and skill differences, plus tips to shorten or lengthen your run. Read on to get a clear picture of how much time you should plan to invest in Undertale.

Quick Answer: Typical Completion Time
On average, most players finish a single Undertale playthrough in about 6 to 12 hours, with full completion or multiple routes pushing total time to roughly 12 to 25 hours depending on goals and playstyle. This range covers casual play and a typical Pacifist or Neutral run, while more thorough players or those pursuing the Genocide route will spend more time. Keep reading for the breakdowns and factors that create such variation.

Routes and What Each One Takes
Undertale’s core time differences come from its route system: Pacifist, Neutral, and Genocide each change battles, cutscenes, and required steps. To visualize, here’s a simple list many players use to estimate:
- Pacifist: Often on the shorter end if you avoid secrets — around 6–10 hours.
- Neutral: Variable — 6–12 hours depending on choices.
- Genocide: Longer due to mandatory fights — 8–15 hours for many players.
Moreover, these are ranges, not guarantees. For example, encountering puzzles or choosing to explore every optional area will increase time. Conversely, if you skip optional dialogue and move quickly through combat, you’ll land on the lower side of each range.
Finally, factor in replays. Many players do multiple routes back-to-back: a Pacifist followed later by Genocide can double or triple total hours. So plan based on how many routes you want to complete in one play session or campaign.

Speedruns, Casual Play, and Player Skill
Player skill and intent shape how long Undertale takes. For instance, speedrunners use precise tactics to reduce time dramatically. Casual players usually take more time because they explore and read dialog.
To illustrate differences, consider this small table showing typical outcomes by playstyle:
| Playstyle | Typical Single Run Time |
|---|---|
| Speedrun (skilled) | Under 2 hours (specialized routes) |
| Casual player | 6–12 hours |
| Completionist | 12–25 hours+ |
Furthermore, learning curve matters. If it’s your first time with Undertale’s combat mechanics and puzzles, expect to spend more time early on. However, you should get faster on replay because you know where to go and what choices to make.
Therefore, plan your time based on commitment: a weekend afternoon works for a first casual run, while a longer period is better for multiple routes or a full completion effort.

Factors That Add or Subtract Time
Many small things can extend or shorten playtime. Below are key factors to watch:
- Exploration: Searching for hidden rooms, items, and conversations takes extra time.
- Combat Style: Whether you spare or fight affects length—some fights are longer when attempting to spare or manipulate attacks.
- Puzzles and Backtracking: A few puzzles will slow you down if you need hints.
- Dialogue: Reading every line increases immersion and time.
Additionally, interruptions matter. If you play with frequent breaks, the clocked experience feels longer even if the in-game time is identical. Also, cultural or language differences might make players read more carefully, adding minutes or hours.
Finally, accessibility options like checking guides or using walkthroughs will reduce time, while intentionally avoiding spoilers will increase it.
Replayability and Multiple Endings
One of Undertale’s core appeals is replayability: the game changes significantly based on choices. That means most players don’t stop at a single completion. Here is a quick breakdown of common replay paths:
- Pacifist first, then Neutral or Genocide
- Neutral to see alternate outcomes
- Genocide as a final, often longer and harder path
Moreover, each additional route typically takes as long as the first, though replays are often faster because you skip areas or already know solutions. For example, a first Pacifist run might feel like 8–10 hours, but repeating Pacifist is often shorter.
Thus, if you want to experience all endings, multiply your single-run estimate by the number of routes you plan to play. Many completionists report total times in the double digits when aiming for every branch and secret.
Platform Differences and Loading Times
Platform can slightly affect time due to loading speed, controls, and added features like save states. The difference is usually small, but it matters to precise speedrunners or those who care about comfort.
| Platform | Typical Impact on Playtime |
|---|---|
| PC | Fast load, easy modding, often quickest |
| Console (Switch/PS) | Comfortable controls, small load delays |
| Mobile | Portable but tap controls may slow precise actions |
Furthermore, some players use console portability to play in short bursts, which spreads the total time over more days. In contrast, PC players might play longer uninterrupted sessions.
Therefore, pick the platform that matches how you like to play. If you want the fastest single-session experience, PC often wins. For relaxed play across commutes or breaks, handhelds are great.
Secrets, Side Content, and 100% Completion
Want every secret and hidden conversation? That choice will increase playtime considerably. There are a few optional fights, hidden dialog sequences, and small puzzles that completionists chase.
Consider this small list of common completion tasks:
- Collectible items and hidden areas
- Completing optional boss encounters
- Unlocking all dialogue variations and scenes
Additionally, some of these objectives require multiple routes or meeting specific conditions. For example, a secret may only appear if you meet certain choices from an earlier run. That forces replays and boosts total time spent.
So, if you’re aiming for 100% knowledge and content, budget extra hours. Many players doubling back to find everything report spending two to three times the length of a single casual run.
Tips to Shorten or Lengthen Your Playtime
If you want to finish faster, focus on main objectives and avoid optional areas. Conversely, if you want to savor the experience, slow down and read every bit of dialogue and explore thoroughly.
Here are practical tips to manage your time:
- Shorten: Use a minimal walkthrough, avoid optional fights, and prioritize progress over exploration.
- Lengthen: Read every line, pursue optional content, and try different dialogue choices.
- Balance: Save before big choices so you can experiment after a short run.
Moreover, plan sessions. If you only have a few hours, aim for a single segment (like a boss or area). If you have a full evening, you can likely complete a route. Also, use community resources or speedrun summaries to identify time sinks if you want to skip them.
Finally, remember the goal: play in a way that maximizes your enjoyment. Whether you rush or dawdle, Undertale rewards both approaches with a memorable story and moments that stick.
In summary, the time to complete Undertale varies widely: expect roughly 6–12 hours for a standard first run, and plan for more if you want to see every outcome. Choose your route, platform, and pace based on how much time you have and how deep you want the experience to be.
