DONT SWIM Difficulty Tier List
Which rooms wipe lobbies — ranked by fail rate, panic factor, and recovery options.
How this tier list is ranked
This is a room-threat tier list for DONT SWIM, not a PvP character meta. We rank hazard types by how often they cause swim fails or cascade wipes in public lobbies, how little recovery they offer mid-mistake, and how badly they spike during 20-player chaos. Criteria:
- Instant-fail potential (swim state)
- Reading difficulty (lighting, timing windows)
- Multiplayer interference
- How often creators highlight the room in wipe compilations
Use it beside the Level Walkthrough and Controls. When patches reshuffle stages, we adjust notes on the Updates hub.
S tier — highest wipe pressure
Squish / crushing walls
Red danger cycles punish impatience. Players jump early, bounce, and swim. In full servers someone always enters the window late and body-blocks the safe tile. Master the full open/close loop before you move.
Rising water routes
Vertical timers delete sightseeing. Coin greed is the silent killer. If your brightness is low, the climbing line is harder to read, which stacks with dark-room problems.
Prep: climb first, loot never, call the rise in chat (Players).
A tier — high skill expression
Rotating platforms
Fair once you wait for full-face landings, brutal if you jump on corners. Ping and low frame rate make leading lips look safer than they are.
Sinking floors
Constant relocation. AFK moments and emote clips convert directly into fails. Groups that stack on one tile create contested exits.
B tier — dangerous when rushed
Dark rooms
The geometry is often simpler than S-tier rooms; the lighting lies. Zoom out, silhouette gaps, and refuse blind sprints. Solo players actually fare better here than crowded lobbies that kick up visual noise.
Dense platform grids
Lots of pads, little forgiveness on diagonal hero jumps. Camera spin is the real enemy. Plot three landings ahead.
C tier — teaching rooms
Early straight platforms and wide ledges
These exist to imprint the “do not swim” rule. Still fatal if ignored, but recovery space is larger. Perfect for the practice loop in Getting Started.
Finale ranking — Worm chase
The Worm is its own category: not a platform puzzle, a pathing stress test. Grab fails equal swim fails. We slot the finale as S-tier pressure for first clears and A-tier once you have a memorised dry kite. Full tactics: Survive the Worm.

How to train with the list
- Pick the highest tier that currently kills you.
- Open the matching section of the Level Walkthrough.
- Change one variable per attempt (camera, timing, route).
- Log whether the death was swim, crush, or Worm.
- Only then move to the next tier threat.
Multiplayer modifiers
Every room climbs half a tier in a full 20-player server:
- More hitbox noise on pads
- More accidental shoves toward water
- More contested safe windows
Counter with spacing rules from the Players hub. If your friend group only queues stacked, expect S-tier rooms to feel impossible until you stagger jumps.
Scripts and the tier list
Automation that auto-completes S-tier rooms hides your weaknesses. If you still want to experiment, keep it on an alt and read the Scripts disclaimer. Fair clears teach the ranking better than ESP ever will.
Codes impact
No active codes currently change room difficulty. When cosmetics or boosts arrive, we will note whether they alter movement enough to shift tiers.

Treat this list as a heatmap, not destiny. A calm camera demotes most A-tier rooms overnight.
Frequently Asked Questions
Quick answers for Poolrooms runs and Worm escapes.
What does this DONT SWIM tier list rank?
Room and hazard difficulty — which stages cause the most swim fails and lobby wipes — not characters or paid items.
Why are squish walls ranked so high?
Tight timing windows plus multiplayer blocking create bounce-into-water deaths even for experienced players.
Is the Worm part of the tier list?
Yes. We treat the post-clear Worm chase as S-tier pressure for first clears and slightly lower once you know a dry kite route.
Will updates change these tiers?
They can. After major patches we revisit rankings and note changes on the Updates hub.
