About This Reference Site
This site documents one betting format — the timed high-low round known as big small, and sold in various places as colour prediction or colour trading. We do not run rounds, hold balances or take payments, and we do not accept commissions to recommend operators. What we publish is a description of how the format works and a set of checks anyone can apply to any build of it.
The editorial rule we work to
Anything we cannot verify, we do not assert. That single rule explains most of what this site does and does not contain. Payout figures, permission lists, round lengths and withdrawal terms are all observable, so we describe them. The finances, ownership and intentions of companies that publish no accounts are not observable, so we do not rank them, score them or reassure you about them.
How a build gets examined
We open it in a browser first and note the multiplier on a winning call. We check whether rounds and rules are readable before any registration form appears. Where an install exists we read the permission list and compare its payout against the web build. Where money is involved we deposit the minimum and withdraw it before anything larger goes in. Every one of those steps is repeatable by a reader, which is the point of describing them.
What is deliberately absent
No mirror lists, because a published address becomes an endorsement that outlives its accuracy. No operator rankings, because ranking things you cannot audit is guessing in a suit. No prediction content, because the digit is generated after betting closes and nothing local can read it. And no earning framing, because the arithmetic of a sub-double payout on an even-money bet does not support one.
Who writes this
People who log their own sessions at minimum stakes and compare notes when builds change. We write in English with the Hinglish search terms readers actually use, because that is how the questions arrive. Where our confidence is low, the text says so rather than rounding up to certainty.
On responsible play
Rounds here resolve in a minute and nothing interrupts a session. That combination is what makes written limits worth more than intentions. Decide the amount before you start, treat it as spent, stop at the round count you chose, and if any of that has become difficult, contact a support service in your country rather than looking for a better system.
Where to start reading
The definition of the format first, then the home page for round types and the cost of an hour. Those two cover the ground that matters before anything else on the site becomes useful.
Corrections
If a figure here is wrong or a build has changed, tell us — write to our inbox. We update pages when something changes rather than on a publishing schedule.
