Case Study: Fumb Games achieves 65% Day 7 retention increase and 700,000+ installs with Tenjin

How to create the biggest “play and earn” crypto game on mobile

Fumb Games, a London-based mobile studio behind Bitcoin Miner, faced repeated launch challenges because many ad networks blocked cryptocurrency advertising, forcing two failed attempts before trying again in 2022 at the peak of play‑to‑earn. To relaunch effectively, Fumb Games leaned on Tenjin’s advertising analytics stack — including ad attribution and session‑based ad revenue LTV — to measure and optimize user acquisition and monetization.

By combining Tenjin’s UA and analytics tools with ZEBEDEE’s web3 payments, Fumb Games created an ad-funded, play‑to‑earn loop that pays players satoshis for playing. The Tenjin-powered strategy plus ZEBEDEE rewards drove >700,000 installs, about one‑third of players creating web3 wallets, an average of eight withdrawals per player per month, a >50% overall retention uplift and a 65% increase in day‑7 retention, turning Bitcoin Miner into one of the most successful web3 mobile games.
