Answer Capsule

Coindle is a daily crypto guessing game where players identify a mystery cryptocurrency in 6 tries using clues across 6 categories. Pyth Hermes Price Feeds power the live price display, 24h change calculation, price tier game logic, and 90-day sparkline charts for ALL of the 140+ pyth verified coins in the curated pool. Available as a web app (coindle.xyz), Discord bot, and Farcaster mini app.

What It Does

Coindle is a quick and engaging way to test your ball knowledge about coins and learn about the coins. With accurate price data, players can start their morning with a daily crypto themed puzzle.

1. Live Price Display

Every coin in the game shows its real-time Pyth price with a green pulse indicator. Prices update every 30 seconds via the Hermes `/v2/updates/price/latest` batch endpoint. All 141 coins fetched in a single HTTP call.

2. 90-Day Sparkline Charts

Historical prices sampled every 3 days over 90 days (31 data points) via Pyth’s timestamp endpoint. Rendered as SVG sparklines to give players a visual hint about the coin’s price trend.

3. 24h Price Change

The Hermes historical endpoint (`/v2/updates/price/{timestamp}`) provides the price from 24 hours ago. The percentage change is displayed alongside current prices throughout the game — on guess rows, the answer reveal, and the game-over card.

4. Price Tier Game Logic

Pyth prices are mapped to 10 logarithmic tiers (from <$0.0001 to >$10,000). When a player guesses, the price tier comparison tells them if the mystery coin is in the same price range (green), adjacent range (yellow), or far off (red) with directional arrows.
