Seven Apps, One Wall of Silence
Every one of the seven apps in this family blocked our check by region. We're publishing what little that itself tells us, rather than guessing at the rest.

This is the thinnest platform page we publish, and that thinness is itself the finding. All seven apps grouped here returned a geoblock from our check location, so most of what we'd normally report, bonus figures, registration fields, game lists, simply isn't available to share.
Why we have almost nothing to quote from these seven homepages
Every one of the seven domains in this family is geoblocked against the region we checked from. On several, the visible page loaded but the registration screen itself returned no readable content; on others, the browser session ended at "about:blank" before any registration markup appeared at all.

What the family name is based on
We group these seven together by their matching page structure and shared registration template, which our fingerprinting labels as a referral-code build. We were not able to independently re-confirm every wording detail of that referral flow from the region we checked from, which is exactly why this page is short on quotes: we'd rather group by matching structure and say plainly what we couldn't read than invent screen text for seven separate apps.
The one thing the wider category shares
All seven sit inside our colour-prediction category, alongside our invite roulette and agency center families, where we could read enough to confirm the same "guess the number, guess the colour" mechanic on the sites that did render for us. There's no reason to assume this family works differently, but we're not asserting it does either.
Geoblocking is not proof of anything by itself
A site restricting a specific region can have entirely ordinary reasons behind it. What makes this family worth flagging as a group is that the block was total: seven for seven, with no exceptions, on a family that also shares a registration template with the invitation-code mechanic we cover in our dedicated guide.
What we could not verify
- Any bonus figures, minimum deposit, or withdrawal terms for any of the seven apps.
- Whether the invitation code field is mandatory or optional on any of them.
- Whether the seven share a single operator, beyond the matching template.
Reading a homepage title when the page itself won't load
Even where the registration screen gave us nothing, most of these seven domains still returned a bare page title from the server, just a brand name with no supporting text. That's a thinner version of what we normally capture, and it's the reason this write-up leans on domain records and family grouping rather than the kind of homepage quotes you'll see on our other platform pages.
Why a domain age table still matters here
Even without registration-screen content, the domain ages above are independently verifiable through a public RDAP lookup, regardless of what the site itself chooses to show a visitor from our location. That's part of why our checklist leads with the domain check rather than homepage marketing: it's the one layer that a geoblock can't hide.
How this family compares on age to the rest of colour-prediction
Six of these seven domains fall between 47 and 83 days old, a fairly tight band, with FL88 as the clear outlier at 321 days. That spread is narrower than what we found in the invite roulette family, where the youngest and oldest domains were nearly ten times apart, suggesting this particular template rolled out its current wave of sites over a shorter window.
Common questions
Why is this page shorter on detail than your other platform pages?
Because all seven apps in this family blocked our check by region, we have far less independently readable content to report, and we'd rather say that plainly than fill the gap with guesses.
Does 'referral-code' mean these apps require an invitation code to register?
That's the defining feature of the shared template we grouped them under, based on registration-page structure, though we could not re-confirm every field on each of the seven from our check location.
Is FL88's much older domain (321 days) meaningfully different from the rest?
It's older than its six family members by roughly 240 days, but we have no more visibility into its registration flow than we do into the others, since it was also geoblocked.
Should a full geoblock across an entire family change how I read it?
It should at least make you cautious about any claim you see repeated about these apps secondhand, since we, and likely other independent reviewers checking from the same region, can't verify the underlying screens ourselves.
