Your catalog can be perfect — a clean price ladder, passes and products in the right roles — and still convert at zero, because conversion doesn’t happen in the Creator Hub. It happens in a ScreenGui, at the moment a specific player looks at a specific prompt. The five mistakes below all live in that UI layer, and all five are structural: detectable from the game’s UI tree before launch, no analytics required. Our audit engine checks every one.
1. The purchase prompt with no way out
The single most damaging pattern we flag, and the only UI rule our engine treats as critical (purchase-prompt-missing-close-button, a 15-point penalty): a purchase prompt with no visible close or dismiss control.
Think about what a non-dismissible prompt communicates. The player opened your game to play; you’ve put a wall between them and the game that only money appears to remove. On Roblox specifically — a platform whose players have deep pattern recognition for scam UI — this reads as hostile, and hostile reads as downvotes and abandoned sessions. The prompt doesn’t need to convert to damage you; it only needs to be seen.
The fix: every prompt gets an obvious close button. Not a 10-pixel target in the corner — an honest, visible exit. A player who declines politely today is a player who is still in your game tomorrow.
2. The price that appears at the last second
A “BUY” button with no number on it forces the player to click through to Roblox’s confirmation dialog just to learn the price (purchase-prompt-missing-price-label). Every one of those clicks ends in either a purchase or a small breach of trust — the player feels walked into a decision they didn’t have the information to start.
Hidden pricing also invites disputes: a player who didn’t clearly see “499 R$” before confirming is far more likely to feel the charge was a mistake. The fixis almost embarrassingly cheap: put the Robux price on the button itself. If your button design “doesn’t have room” for the price, the design is hiding the most decision-relevant fact on the screen.
3. The shop with nothing behind it
The inverse of most monetization failures: a shop screen exists, but the game has no game passes and no developer products at all (shop-ui-without-products). We see two versions. Either the build is unfinished — the shop shipped before the catalog — or the shop sells soft currency that has no Robux on-ramp behind it, a dead-end economy wearing a shop’s clothes.
Either way, the screen spends the scarcest resource you have — player attention at the moment they’re curious about buying — on a surface that structurally cannot convert. The fix:back the shop with real products before you ship it, or don’t ship the shop yet. (What to build first is its own question.)
4. The products no path leads to
Mistake three’s mirror image, and the more expensive one: the catalog exists, but no shop screen does (monetization-without-shop-ui). Discovery now depends entirely on whatever scattered purchase prompts you’ve wired up. If those exist, this is a warning — your products are reachable but hard to browse. If they don’t — no shop screen and no prompts — our engine escalates the finding to critical, because your developer products may be literally unreachable. In Studio you never notice: you know the products exist because you made them. Players only know what the UI shows them.
The fix: one discoverable shop surface — a persistent shop button opening a browsable screen — as the canonical path to everything you sell, with contextual prompts layered on top, not instead.
5. Prompt spam
Each contextual prompt seems locally reasonable: a revive offer on death, an upsell at the level gate, a bundle on join. But players experience the sum, and past six distinct purchase prompts (high-purchase-prompt-count) a game starts to feel like it’s selling at you from every direction. Aggressive-feeling monetization suppresses exactly the goodwill that purchasing runs on — and it compounds with every other mistake on this list.
The fix: consolidate. Keep the two or three highest-context prompts (the revive at death is genuinely useful), route everything else into the shop, and let one surface do the selling.
The pattern underneath all five
Every mistake here is a trust failure, not a pricing failure. A player who can always leave, always sees the price, and is sold to in one honest place will forgive a mediocre catalog. A player who feels trapped or tricked will not forgive a great one — no price ladder survives a hostile prompt. And because all five failures are structural, you don’t have to wait for angry players to find them: the pre-launch checklist covers them by hand, or the plugin reads your UI tree and flags them in about a minute.
