Aviasales X Tochka Bank: Mini-app In Telegram With Gamified Captcha Mechanic

Objective

Aviasales, a flight-booking platform, partnered with Tochka Bank to drive rapid user acquisition to Aviasales for Business, a B2B portal. The collaboration leveraged a Telegram mini-app with playable CAPTCHA mechanics to create a frictionless, low-barrier entry point for prospective business customers.

Solution

A Telegram mini-app featuring a linear three-stage interactive structure where users progress through sequential CAPTCHA-style puzzles without intermediate screens. Incorrect attempts trigger soft overlay hints to guide users back to the current step. Upon completion, an animated final screen with a clear call-to-action directs users to Aviasales for Business. The mini-app provides direct access via shareable links and allows repeatability. Development was completed in three weeks using Telegram WebApp API.
