The challenge

The client came to us with the idea of popularizing their existing cryptocurrency, VOW, by developing a gaming platform where players need crypto tokens to participate. The product needed multiple integrations and had specific security requirements to ensure safe currency transactions.

Project management

  • Our goal was to create a user-friendly application where players can deposit cryptocurrency and compete against friends.
  • Players advance through levels by winning consecutive rounds, aiming to win one million dollars.
  • Our second objective was to develop an admin panel for the client to oversee user accounts, prize levels, and withdrawal requests.
  • The third part of the project scope was integrating third-party services for SMS verification, payment processing, video streaming, and cryptocurrency transactions.

Pitfalls

Midway through the project, we hit a big snag when we realized Apple might not approve our product release. To work around this, our frontend developer quickly built a web-based product version in just a month. This proactive move kept our project on track.

The project start wasn't as smooth as we planned. We tackled this by improving transparency and revamping our processes. Better communication and workflow refinement turned things around, and the client ended up happy with our work.

We encountered technical issues with video streaming technology, initially not suitable for cross-platform development. This required creative problem-solving and adaptation to ensure smooth operation across platforms.

Functionality

The gameplay is simple: Two players bet $1 each; the winner takes the $2 pot and advances to the next level. With each consecutive win, the stakes double ($2, $4, $8, $16, etc.), and the winner must find a new opponent at the same level. If a player wins 20 times in a row, they get $1,000,000.
  • At every fifth level, the player can cash out the winnings, choose a prize, or continue battling for $1M.
  • The user can play against a bot, invite others from the list to join the game, or battle a randomly selected player.
  • While playing, users can grant access to the device camera and sound to communicate in real time and send each other emojis.
  • Users can report and ban each other.

Admin panel

An admin panel was essential for user management, security monitoring, content oversight, financial management, analytics, and regulatory compliance, ensuring smooth operation and integrity. The RPS Millionaire's control system includes three main parts.
Admin panel

User management

  • Admins can view user feedback and all generated reports in a list format.
  • Admin can view reported users and ban them based on report reasons.
  • Admin can cancel reports if no ban is necessary, removing them from the list.
  • The super admin can create, delete, or replace the admin panel users and determine the role and its access level.
  • The super admin can change personal data, change passwords, and deactivate other admin panel users.
  • The analytics section can be arranged by period and contains statistics on the number of games, wins, losses, and draws.

Prize level management

  • Admin can select prize levels and add items.
  • Items are added only after admin confirmation.
  • Admin can delete prizes from any level and modify award descriptions and photos.

Withdrawal management

  • Admin can view and manage all withdrawal requests and mark them as done.
  • Admin can view all completed withdrawal requests.

Integrations

The app's smooth functioning was impossible without multiple third-party integrations.

  • Twilio SMS verification
  • Video streaming for cameras
  • Tapjoy integration
  • Crypto's endpoint integration
