2Report quest+50

Take a photo. Gemini fills in the form.

Point your camera at a pothole, a dead streetlight, graffiti or a blocked sidewalk. Gemini checks that the photo shows a real street problem, then returns a category, a severity and a one-line description.

  • Selfies and food pics earn nothing. Photos that aren't street problems are turned away.
  • It reaches the City. The reward screen has the location and details ready to paste into Tempe's 311 form.
  • Share it. A street cred card shows your points and neighborhood, never your location.

Player reports next to the City's own records

Every report becomes a pin, colored by severity. Turn on the City layers and the same map shows public City of Tempe data, so you can see where the gaps already are.

  • From the City: ADA Transition Plan findings, bus stops with no shelter, drinking fountains, park restrooms and community food sites.
  • Tap a pin for the photo, the description and a button that sends it to Tempe 311.

6Points on Solana

Every point is a token you can look up

Each award is minted as a CIVIC token on Solana devnet, to an address that belongs to that player. Your profile links straight to your wallet on the explorer.

  • Devnet is a test network. The tokens aren't worth money, and nobody is ever asked for a seed phrase.
  • The game doesn't wait for the chain. Points count right away and the award shows as pending until the transaction lands.

7Local Deals

Spend points around the corner

Points buy small things at spots near you. Report a street problem within about two blocks of a shop and its price drops to the neighborhood rate.

  • These are demo deals. The partner spots are examples for the hackathon, not signed-up businesses.
  • Redeeming shows a code to read out at the counter, and takes the points off your balance.
Local Deals: Mill Ave Coffee at 50 points instead of 100, and three other spots.
