About FreeSpinsIndex

FreeSpinsIndex is an independent comparison site with a narrow brief: free spins offers at crypto and international online casinos, and nothing else. No sportsbook reviews, no "top 100 casinos" filler — one promotion type, covered properly.

How we test

Every offer in our index is claimed on a real, funded account before it is listed. Over the past twelve months that meant 47 claimed offers, 31 completed wagering requirements and timed withdrawals at all ten ranked casinos. For each offer we log the claim flow, the full bonus terms (spin value, wagering, max bet, max cashout, expiry, eligible games), and the cashout experience — then run the numbers through the same expected-value model you can use yourself in the Free Spins Value Calculator.

Rankings are re-checked monthly. When a casino changes its terms, its score changes; several positions on the current top 10 moved this spring for exactly that reason.

How we make money

Casino links on this site are affiliate links: if you sign up through one, the casino may pay us a commission. Two rules keep that honest. First, commissions never influence position — rankings come from the test scores, and the math is published on every page so you can check our work. Second, you never pay more or receive less by using our links; the offers are identical to what the casino shows everyone.

What we are not

We are not a casino, we take no bets, and we hold no player funds. We do not provide gambling services to anyone under 18, and we encourage every visitor to read our responsible gambling page before claiming anything. Free spins are entertainment with a price tag that statistics eventually collect — our job is making that price tag visible before you commit.

Corrections

Casino terms change weekly and we occasionally lag. If you find an offer whose live terms differ from what we list, we want to know: email hello@freespinsindex.com and we will re-verify within a few days. The "verified" date printed on each comparison table tells you when we last checked.
