Display modes
Each game works as a half-screen panel that keeps the voice room visible, or full-screen for focused play.
- Half-screen panel above the room
- Full-screen mode
- Responsive layouts for phones of every size
Platform
The platform behind the games
Games, wallet connection, security and reporting — designed for operators who already run their own coins economy.
Seamless single wallet
Player coins never move to us. During play we call your wallet API, and your balance stays the single source of truth.
- Debit, credit and rollback operations
- Batch requests for multi-player rounds
- Idempotent request ids so retries are safe
- Configurable batch size and concurrency
Security
Requests between our servers and yours are signed and time-bound.
- Standard Webhooks signatures (HMAC-SHA256)
- Timestamp window and request-id replay protection
- Secret rotation with an overlap period
- One-time launch codes for player entry
Realtime rooms
Round state is pushed to every player over Server-Sent Events, so everyone in the room sees the same countdown and result.
- Server-Sent Events streaming
- Shared rounds for the whole room
- Automatic reconnect
Sandbox and production
Two separate environments with their own wallet settings, secrets and game selection.
- Sandbox: sandbox.sentosatower.com
- Production: games.sentosatower.com
- Production access after review
Console and billing
A prepaid model with transparent reporting.
- Prepaid USD balance with top-ups
- Daily consumed coins per game
- Monthly reports and CSV export
- Append-only ledger of every entry
