Colour and Number Prediction Apps

The 25 apps in this category share one core mechanic, whatever brand name sits on top of it: predict whether a number will land big or small, odd or even, or guess which colour (usually red, green, or purple) a round will land on, ahead of a short countdown.

Fifteen of these 25 apps fall into one of three shared-template families we've identified: referral code (7 apps), agency center (4 apps), and invite roulette (4 apps). All three of those families showed at least some geoblocking on our check, meaning we could not fully view every registration screen inside them from our location.

That pattern is heavier here than in our slots category, where none of the shared templates we found were geoblocked. We don't have a confirmed reason for the difference, only the pattern itself across our September 2026 check.

Ten of the 25 apps in this category didn't match a shared template we could group with confidence, so treat those standalone listings on their own terms rather than assuming they follow the referral-heavy pattern common to the three named families here. A handful of them still display similar big-or-small guessing panels, they simply didn't share enough of the surrounding page structure for us to fold them into one of the three named groups.

This category also carries the heaviest concentration of invitation-code registration flows in our directory. If you're new to why that box shows up so often, read our invitation code guide before going further into any single app below, and see our checklist for the wider set of signals worth checking regardless of which template an app runs.
