Waterpark Simulator Achievements — All 71 & How to Unlock Them (2026)

Waterpark Simulator has 71 achievements on Steam, confirmed by the official global achievement page. Most of them are long counters — clean 1,000 trash, mop 1,000 puddles, sell 500 hot dogs — and the rest are prestige milestones, Museum quest completions, and one-off comedy moments. The single hardest achievement sits at a 0.4% global unlock rate (5-star on Hard difficulty), and a full 100% run lands in the 35–50 hour range. This guide lists every achievement with its unlock condition and global rate, then breaks down the hardest ones and how to grind the long counters efficiently.

Here's what you'll learn:

• The exact count on Steam vs the console lists (and why they differ)
• The full 71-achievement table with conditions and global rates
• The easiest achievements nearly everyone gets
• The hardest achievements and their realistic unlock paths
• How to grind the long counter achievements without burning out
• The Museum/Yogi quest achievements and the one-off comedy unlocks
• What 100% actually costs in time

How Many Achievements Does Waterpark Simulator Have?

71 achievements on Steam — the global achievements page lists all of them with player percentages. The numbers you'll see elsewhere vary because the console lists are still consolidating:

• Steam: 71 (authoritative, from Steam Community stats)
• TrueAchievements: 59 listed at the time of writing (Xbox list snapshot — the gap is pending trophy data, not missing content)
• TheGamer: 55 in their launch-window guide

The Steam list is the ground truth for now: the game is only weeks past its July 31, 2026 1.0 launch, and third-party console lists are still catching up. Expect the Xbox/PS5 counts to converge on 71 as the lists update.

The Full 71-Achievement List

The Easiest Achievements

The first handful are effectively participation trophies — 94% of players open the park, 92.5% build a first slide, and 83.8% finish the tutorial. The first star lands at 83.4%. If you follow the beginner guide through one star, you also pick up the first trash/mop/repair counters and "Slidekick" (first hire) on the way.

The Hardest Achievements (and How to Unlock Them)

The prestige top of the ladder is where the global rates collapse:

• Unstoppable Resort (0.4%) — 5★ on Hard difficulty. Hard isn't mechanically different, it's slower and tighter: higher maintenance, refunds from displeased guests, and fines for firing staff. Expect a 40+ hour save.
• Above the Stars (0.9%) — Diamond prestige: after 5★, earn $1,000,000 cumulative and build one 6-Prestige Wonder Attraction (one Museum tree completed far enough). The full route is in the end game guide.
• City Legend (1.5%) / King of the Coast (1.4%) — 5★ on the City and Beach maps. Prestige is map-scoped, so both maps need their own 5★ run.
• Pool-ution Solution (0.9%) — clean 500 pool poops. The grind path: more guests + fewer toilets nearby increases incidents; a fast method is deliberately keeping small pools dirty (players report the poop cleaning counter climbs fastest with high guest density in one pool).
• Nothing Left to Learn (8.0%) — unlock all research. It's a long grind because late research costs 15–20+ points and a paced park banks only a handful of research points per day. The research points guide has the farming loops.

Long-Counter Achievements: Efficient Grind Routes

Most of the list is counting, so efficiency beats effort:

• Trash (100/500/1000) and Mop (100/500/1000) — let mess accumulate, then clear in one pass. Keep bins sparse in one zone and mop puddles in bulk. The tips & tricks guide covers the "two good pools over four mediocre ones" guest-pressure trick that keeps counters flowing.
• Sell 500 hot dogs / lemonades / ice creams — stock one stand type hard, price it to sell, and let a vendor run it while you do everything else. These counter on cumulative sales across the save.
• Save 100 drowning guests / Push 100 panicking guests — more guests, more incidents. Crowd a pool, keep one life ring in hand, and throw rings into the water at day start so panicking guests bump into them (saves you the run too).
• Catch 200 no-bracelet guests — hang out at the gate during rushes; the front-gate patrol is the tested method.
• Clean 500/1000 pool poop — guest density is the lever; see Pool-ution Solution above.

Museum and Yogi Quest Achievements

Three achievements come from Yogi's questline at the Museum (the Wellness theme): finish his 3★ quest for "Path of Slight Enlightenment" (14.2%), the 4★ quest for "May the Steam Be With You" (6.2%), and the 5★ quest for "Zen and the Art of Pool Maintenance" (4.4%). These are star-gated, so they arrive naturally if you're pushing the prestige ladder — the walkthrough has the Museum timing, and "Enlightenment Isn't Cheap" (2.9%) appears tied to the Museum's currency system (exact trigger still being confirmed by the community).

Hidden and One-Off Achievements

A handful of achievements need you to do something specific once:

• Mist Opportunity — use the spray can (research unlock; 22.0%)
• Hot Fix — repair an attraction within 5 seconds of it going out of order (camp a frequently-breaking ride)
• Trumpet Solo — play a song on a trumpet (14.6%)
• Don't Look Down — build a 5-star diving board (13.4%)
• Slide Architect — make your first custom slide (2.4%)
• The Bigger They Are… — fall from 15m (use a tall slide or rooftop)
• Punchline Delivered / Human Canvas — hit a visitor with the boxing glove / paint a visitor
• High Above the Park — ride a zipline (6.1%)
• Fresh Look — customize your character (28.7%)

How Long Does 100% Take?

Roughly 35–50 hours: about 18–20 hours for the main run, then the tail — Diamond, both map prestiges, the Hard 5★, and every long counter — is a marathon, not a skill check. The how long to beat guide breaks down where the hours go. The good news: almost nothing in the list requires multiplayer or glitches; it's patience, counters, and three separate prestige runs.
