What drives the score
How to read this
Every input gets a grade, S to D, read from the buyer's side. The score is multiplicative, so an input only counts as raising when it sits near the top of its own scale. Anything with real room left is holding the score back, because that room is the gap to 100. ▲ marks a lift, ▼ a drag or a dock, ? an input we do not have, • a fact this genre's score does not use. The exact weights stay secret.
The value story
It has never been cheaper than $0.98. That was December 2017. It has been discounted 83 times in the 14 years tracked here, typically at 89 percent off, with about 7 weeks between sales. Today it is at full price. The last sale was about 13 weeks ago, and on this game's rhythm the next one tends to arrive within 7 weeks.
Value puts it in the top 6 percent of the games it competes with. It is better reviewed than 87 percent of its genre. Among the games that feel like it, Suicide Guy ($5.99, scores 74) beats it on value, while it beats Moss VR ($19.99, scores 57).
77 from critics against 85 percent from players, and the player number comes from people who own the game.
Of the 382 Steam-purchase reviews this site sampled, 1 comes from a buyer who refunded the game, sampled from reviews written March 2020 to September 2026. Inside the two-hour refund window, 68 percent of the 232 reviews written there were positive, against 85 percent overall, and those are 13 percent of everything written about it.
Finishing takes 6.3 hours; clearing it takes 16, which is 2.6 times the campaign.

What players say
Quantum Conundrum will surely please fans of Portal as it's essentially the same game, albeit with a few missing quirks that made the latter so beloved and iconic. In Quantum Conundrum, you play as a boy visiting their (totally-not-mad) scientist uncle's clifftop mansion, only to find that your uncle has gone missing! Whoa! However, he's not quite missing so much as… "disembodied." You hear his voice during your...

Quantum Conundrum scores 63/100 on the BANG Score (fair value). The BANG Score rates what a game is worth for the money. Via Steam BANGERS. https://steambangers.com/game/200010/quantum-conundrumThe BANG Score is one number for value, 0 to 100: price against how it reviews and how long it was built to be. It answers the money question and stops there; whether the game is for you is still your call.
Reviews set the ceiling and price moves you inside it, so a cheap game that reviews badly cannot climb. Ratings from few reviewers are shrunk toward the middle, so 100 percent from nine people does not outrank 96 percent from ninety thousand. Length comes from HowLongToBeat where it can be matched, measured against a per-genre floor so a five-hour narrative game is judged against other narrative games rather than against a sixty-hour RPG. Where no verified length exists the score says so and carries a dock, because the biggest input is then a guess. The full method, including where it is weak → Steam reviews as of Sep 6, price as of Sep 24.
