Challenge Card · race the other teams

Pinch the Skyline

Use forced perspective so your teammate looks like they're holding, pinching, or pocketing a building. Photo: the illusion, clearly working. Feet stay on the sidewalk the whole time.

  • Photo proof
  • 12 pts
  • 1 Quest Coin
An example Challenge Card: the first team whose photo checks out takes the points.

Want to get in on the fun early?

The Side Quest is open for beta testing on TestFlight, Apple's free app for trying apps before they launch. Install TestFlight, tap the button below, and you can start a quest today. Everyone in a quest needs the app, so send the link to your crew too.

Needs an iPhone or iPad with iOS 18 or later. A beta can have rough edges: if something looks wrong, tell us at contact@mobileside.quest.

How it plays

  1. Gather your crew

    One player hosts: they set The Arena, the stretch of town you'll play in, and share a six-character invite code. Up to eight players join and split into teams, or go solo.

  2. Race the board

    Three Challenge Cards are always up for grabs. Tap Start, do the challenge, and send your proof: a photo, a video, a check-in, the route your phone recorded, or a climb or walk it measures. The first team whose proof checks out takes the points, and rival teams vote on the photos. If a team gives up on a card, the prize grows for everyone else.

  3. Play your private hand

    In team and couples quests, every player also holds up to three Private Cards: small dares and sneaky observations. Send the proof to your teammate (or partner), score for your team, or veto a card that doesn't suit you, at a small cost.

Most points when the quest ends wins. Ties go to the team that completed more cards, then to the team that earned more Quest Coins.

Ways to play

  • Solo / free-for-all

    Everyone for themselves. Two to eight players, each their own team, racing the same board. Solo plays the Challenge Cards on the board only: there are no Private Cards.

  • Team

    Teams of two, up to four teams. Made for friends and family on a trip.

  • Couples

    Couples vs Couples (two to four couples) or Partner vs Partner, head to head. The host sets a spice level from 0 to 4 for how playful the cards get, and the top two levels ask every player to opt in first.

Made for real trips

  • Invite-only. Quests are joined with a code from the host. No matchmaking, no strangers.
  • Private by design. There is no public feed. Proof photos and videos go to the players who review them, and Quest Memories go only to the players in your quest. When the quest ends you can save its album to your photos, and photos and videos are deleted from our servers 7 days later. The app can keep your own copy on your phone, if you leave that setting on.
  • No ads, no tracking. We don't sell your data or run third-party analytics.
  • Works in any city. Challenge packs are written to work wherever you land, and some cards send you to real places near you, like a cafe, a park or a landmark. Hosts can filter out swimming, crowds, alcohol, spending, and more.

Rated 17+, played in the real world

The Side Quest is rated 17+ and isn't intended for children. It sends you out into public places, so keep your eyes up, watch traffic, stay off private property, don't climb anything, never play while driving, and never photograph identifiable strangers without asking. You never have to do a challenge that feels unsafe. Read the safety tips.
