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.

What players say

Graphics are terrible, game is simple and based more on luck than talent at most points, it's repetition and attempt to surprise... well, aren't too exciting. However, I like it and I don't know why. I keep playing it and everyone loves to watch and join in turning it into an awkward group game where I can't drag stuff where I need to because too many people are pointing at my screen.
Freedom FriesRecommendedafter 20h1 found this helpfulRead on Steam
Easy little Bejewelled battle monsters game, however title should be 'You have to build 3 boats to get all achievements' Cost a few dollar bucks and got 30 hours out of it so can't complain,- however would of been about half that if didn't want all the achievments Better than 1000
SwaintonbombRecommendedafter 34hJan 2026Read on Steam
Update: AFTER HOURS AND HOURS AND HOURS... All I wanted was to get all the achievements. This ♥♥♥ demonic bastard game, deleted my ♥♥♥ save, again. It had done it before. I figured it was because I'd not played in a while something must've gone wrong. Now it has deleted it twice. NEVER BUY THIS GAME. This is a great sequel, and it does a lot of things really well. Except no, no it doesn't. See, 1000 was a great...

[![BANG Score](https://steambangers.com/api/badge/290890)](https://steambangers.com/game/290890/you-must-build-a-boat)

The 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 20, price as of Sep 24.

A number here look wrong? Tell me what it got wrong and I will look at the inputs behind it.
