Sloppy Forgeries accuracy scoring judges how closely your painted pixels match the reference picture. The score bar changes as you draw, so you can see whether a stroke helped or hurt your attempt. It sounds simple until you remember that the game gives you no Undo button and no Fill tool.
You copy one of 50 simplified famous artworks with just four to six colours and three brush sizes. It’s supposed to be a slightly hopeless art exercise, but there are useful tools for lining things up, plus a leaderboard for anyone determined to get better.
How Sloppy Forgeries Accuracy Scoring Works

The developer says the game measures accuracy pixel by pixel in real time. As you paint, the bar responds to how the current canvas compares with the target. A big shape in the right place might help more than a lovely little detail painted in the wrong corner.
Playful Systems hasn’t published the calculation behind the score, so there’s no verified colour-difference formula or secret point bonus to exploit. What you can see while playing is the live feedback. The best approach is to look at the reference, make a change and see whether the Sloppy Forgeries accuracy scoring bar improves.
Why You Only Get Three Brushes
There are three default sizes, described by the developer as medium, big and too big. You choose from a tiny palette of four to six colours. You can’t undo a stroke or fill an entire area at once, which means a broad brush is fast but can easily cover parts you wanted to leave alone.
Use the large brush when you need to block in a big area, then switch when you’re trying to place smaller shapes. That’s practical advice rather than a hidden scoring trick: the entire Sloppy Forgeries accuracy scoring challenge comes from working with an intentionally limited set of tools.
What Do Pins and Grids Do?
The game includes time-limited assists such as pins and grids. Their job is to help you spot where your version differs from the reference. If the painting looks close but the score isn’t moving, it’s worth checking whether a major shape is too high, low or far to one side.
These assists help with comparison; they don’t finish the picture for you. The developer hasn’t specified exact durations for them, so don’t rely on a supposed timer or cooldown chart. In Sloppy Forgeries accuracy scoring, placement and colour still matter when the assist runs out.
Tiny Brush, Upside Down and Pointillism

Party rounds can introduce random variants including Tiny Brush, Upside Down and Pointillism. The names give you a fair idea of the chaos involved, but the full rule sheet for each variant hasn’t been published. They change how you tackle the picture rather than replacing the basic aim of copying it.
That makes a multiplayer win quite different from calmly practising the same piece in single-player mode. If you’re planning a party, our Sloppy Forgeries multiplayer guide explains the online join codes and the separate two-mouse local mode.
Can You Practise and Compare Scores?
The Masterpiece Catalog gives you 50 artworks to work through, with personal statistics and an individual Steam leaderboard for each painting. Your past attempts go into a local archive, so you can see whether your next attempt is an improvement or a spectacular step backwards.
Sloppy Forgeries accuracy scoring isn’t just a one-off result at the end of a round. You can keep returning to paintings to chase a stronger leaderboard position, then compare the new attempt with your older work.
How GIF Replays Work
The game can turn a painting attempt into a timelapse replay and export the recording as an animated GIF. It’s a neat way to show friends how an apparently sensible drawing turned into a mess. The feature saves a replay for you to share; it doesn’t mean the game posts it to social media automatically.
Wacom drawing tablets are supported too. That might feel more comfortable than a mouse, but the developer hasn’t said tablet input earns different scores. Sloppy Forgeries accuracy scoring is still based on the picture you produce, not the tool you used to draw it.
Try the Score System for Free
A free demo is available on Steam ahead of the planned 13 November 2026 PC release. It was updated on 4 November with better painting descriptions and a fix for ultrawide mouse movement. If you’re curious about the accuracy bar, try it rather than judging the game from screenshots.
The Sloppy Forgeries release date guide covers what is included in the full version. For Sloppy Forgeries accuracy scoring, the main thing to remember is that this isn’t an art contest judged by taste. The game is comparing your pixels with its target, and every wonky stroke counts.
