    Rip on Gemma

    Fairness check

    What to watch in the terms

    • buyback paid only in site coins; coins not convertible to money
    • may void coins/balances without prior notice after errors
    • per-pack maximum card value cap, modifiable
    • buyback rate may be amended at any time

    It publishes a strong provably-fair commit (a SHA-256 hash before payment, seed revealed after) and shows tier odds. It gets a C under the rubric only because Trustpilot is 3.3, from just 4 split reviews, and the buyback is coin-only.

    Checked from Gemma's own pages, terms of service and Trustpilot on Sep 30, 2026. Figures change: check them on the site. How we rate sites.
