Most "hidden gems" lists are one person's taste wearing a trench coat. This one is arithmetic. We took the live-stats snapshot behind our catalog — retrieved August 4, 2026, from Roblox's official games API — and asked a narrow question: which games do the people who play them rate unusually highly, even though their current player counts are modest? The answer is not a list of the best games on Roblox. It is a list of games whose reputations lag their ratings, which is a different and arguably more useful thing.
How we counted
The method is simple enough to check. For each of the 113 catalog games with live stats in the snapshot, we computed a like ratio: likes divided by likes plus dislikes. To keep tiny samples from faking precision, we dropped any game with fewer than 5,000 total votes — which excluded exactly one game, Piggy, at 3,383 votes. A game counts as underrated if it clears two bars at once: its like ratio sits in the top third of the remaining 112 games (91.7% or better), and its concurrent player count at snapshot time was below the catalog median of 3,722. Seventeen games qualified; the twelve below are the top of that list by like ratio, with the other five noted at the end.
Two honesty caveats before the table. Player counts fluctuate by the hour, so treat every "playing" figure as a photograph, not a portrait. And a like ratio measures the satisfaction of people who chose to play and chose to vote — it says a game delights its own audience, not that it would delight you.
Tower defense keeps its fans
The single loudest signal in the data: tower defense games dominate the underrated list. Anime Defenders posts a 96.7% like ratio across 2.09 million votes — with 372 people playing. Its 3.4 billion visits show this was a breakout hit of 2024, a summon-and-upgrade anime TD built around grinding for rarer units; the crowd has moved on, but almost nobody who stayed regrets it. Anime Last Stand is the same story one notch down: 95.7% across a million-plus votes, 346 playing, a content-heavy anime TD with a huge roster and raid content. And Tower Defense X (94.4%, 1,049 playing) is the non-anime pick — a classic-style TD with co-op lobbies and wave maps that scale in difficulty, refining the formula older Roblox TDs popularized. Our tower defense roundup covers the genre's crowded top; this trio is its quiet floor.
The car games nobody talks about
Vehicle Legends holds a 94.4% ratio across 1.49 million votes with 2,380 playing — remarkable consistency for an open-world racing game from 2020. It is built around a deep car list, upgrades, and customization, split between cruising and competitive racing. Car Crushers 2 (93.4%, 2,964 playing) approaches cars from the opposite end: you collect vehicles specifically to destroy them in crushers and disaster scenarios, and its 6.9 million favorites suggest the joke has never worn thin since 2017. Both live on the racing shelf, well below the genre's headline names.
Horror that needs a full party
Specter is the highest-rated horror game in our entire catalog at 95.4% — and had 552 players at snapshot time. It is Phasmophobia-style co-op ghost hunting: a team enters a haunted location, gathers evidence, and identifies the haunting before it identifies them. The likely reason for the gap is structural: it wants a coordinated group, and games that need four friends online at once always poll better than they populate. The broader horror catalog and our horror roundup hold its louder cousins.
Old chaos, still beloved
Two veteran survival minigames cleared the bar comfortably. Zombie Attack (94.3% across 1.45 million votes, 651 playing) is a wave-based co-op shooter — survive the horde, earn credits, upgrade weapons — and its 5.95 million favorites say a great many players intend to come back someday. Super Bomb Survival is the list's deepest cut: a 2015 arena game about outlasting escalating rains of bombs, still rated 93.2% a decade on, with 160 people playing. Neither game has a trend cycle left; both apparently still deliver.
Grinders that aged well
Bubble Gum Simulator is the headline statistic of this whole exercise: 96.8% across 508,654 votes — the highest like ratio of all 112 eligible games in our catalog, trending giants included — with 2,639 playing. It is a classic pet-collecting simulator: blow bubbles for currency, hatch eggs, trade toward rarer pets. Mining Simulator 2 (93.2%) posted the list's smallest crowd at 73 players, and is the same collect-and-trade loop pointed at ores and gear from a well-known studio. The simulator genre churns through fashions faster than any other; these two are what its survivors look like.
Business and generosity
Restaurant Tycoon 2 (93.1%, 2,700 playing) is the tycoon entry: design the space, set the menu, hire staff, and scale a restaurant up — a focused business builder that outrates most of the tycoon shelf. PLS DONATE squeaks in at 93.0% with 3,266 playing, just under the median. With 5.19 billion visits, "underrated" is a stretch historically — it was a genuine phenomenon, a social game where players open booths selling their own gamepasses and donate Robux to each other — but at snapshot time the numbers qualified it fair and square, and the rating says the loop still works for those inside it.
Five more that cleared the bar
The remaining qualifiers, with like ratio and players at snapshot: Ninja Legends (92.5%, 1,176), a classic training-and-rebirth simulator; Arcane Odyssey (92.4%, 778), an ambitious open-sea RPG of magic builds and exploration; All Star Tower Defense (92.0%, 972), the anime TD that popularized the form, 7.9 billion visits behind it; Apeirophobia (92.0%, 1,696), Backrooms horror with environmental puzzles; and Dungeon Quest (91.9%, 690), a co-op loot-grinding dungeon crawler.
What the numbers can and cannot say
A high like ratio on a small population usually means one of two things: a game past its trend peak that kept only the people it genuinely suited, or a game that never trended because its audience was narrow from the start. Both kinds are worth your evening precisely because the remaining players are volunteers, not tourists. What the numbers cannot do is match a game to you — for that, every title above links to a detail page with its live stats, the browse page filters the full catalog by genre and scale, and the trending board shows the opposite of this list: what everyone is playing right now, regardless of how they rate it.
