Where our numbers come from

We only use game data from a source we can name and link to. Upgrade costs and times come from game-file exports or the official wiki for that game. Tier lists and deck rankings come from public match statistics covering a large number of games. We never estimate a cost or a timer to fill a gap. If a number isn't in our source, the tool says so, rather than guessing. Every source is listed on our credits page, and each tool page says when its data was last pulled.

How we build tier lists

Our Brawl Stars and Clash Royale tier lists are built from win-rate and usage data, not opinion. The tier cut-offs are fixed and printed on each page, so the same data always gives the same tiers. Where the sample is too small to trust, we flag it. Our Rise of Kingdoms pairings follow a named community ranking, and our Whiteout Survival hero tiers follow the release order of hero generations, because newer generations are stronger by design. Each page explains its own method.

How we check codes

A code is only listed as active when at least one reliable source lists it as active and none of the others we check says it has expired. When sources disagree, we say so next to the code and lean towards marking it expired, so you don't waste time on a dead code. Every codes page shows the date we last checked. If we haven't been able to confirm any codes for a game, the page says that plainly and is kept out of search results.

What we won't publish

• Leaks or rumours presented as fact. Unconfirmed release dates are labelled as reported, with the source.
• Pages with nothing useful on them. Pages we haven't filled in yet are kept out of search results until they are.
• Paid placements. No game, creator or advertiser can buy a tier, a ranking or a mention.

Updates and corrections

We refresh tool data after balance changes and major updates, and re-check codes regularly. When we find a mistake, we fix it and update the page's date. If you spot something wrong, email [email protected] with the page link and, if you can, a screenshot or source. Corrections are the most useful thing you can send us.

Advertising

ClashHaven may show ads to cover hosting. Ads are always kept separate from our tools and never change what a tool shows, how a list is ranked or which codes we list.
