From brief to −38% CPA: how a Telegram mini-app drove 1,880 slot registrations
An 18-day Telegram campaign in India combined a mini-app demo slot, bot follow-ups and Hindi-localized creatives to cut CPA by 38%. The playbook, step by step.
Telegram traffic keeps outperforming our own expectations. This spring, a slots brand targeting India asked us to test messenger inventory against their usual push sources. The result: 1,880 registrations, CPA down 38%, ROI +141%.
The playbook
- A mini-app with an embedded demo slot — players experienced the product before registering.
- Bot follow-up push 24 hours after first touch, when intent cooled but memory hadn't.
- Hindi-localized creatives instead of translated English.
- Switched to CPA bid strategy after the first 300 conversions stabilized the model.
Why mini-apps convert
Mini-apps remove the install cliff. The user never leaves Telegram, the signup flow is instant, and follow-up pushes reach an opted-in audience at zero extra media cost. For casino and sportsbook offers with instant-registration flows, that friction reduction is everything.
“The demo slot did the selling — the bot just reminded players where to find it.”
If you are running casino or sportsbook offers and have not tested Telegram inventory, you are likely leaving your best CPA on the table.
