How can we help?

Gameplay

Tap once to switch lanes. Dodge red blocks and move into blue absorb blocks. Difficulty and obstacle speed rise quickly. The upper fog begins fading in after about 4 seconds, reaches its maximum at about 18 seconds, and never covers more than 50% of the screen.

All-time rankings

City, country, and global rankings use one persistent all-time best score and have no weekly, seasonal, update, or reinstall reset. Eligible verified scores are published under a public Ranking Nickname. A new account starts with a generated nickname; the player's first custom nickname is free. After that, one rename credit is added at 00:00 UTC on the first day of each month, up to 3 stored credits. Nicknames are 3–16 letters or numbers with optional single underscores and must be globally unique without regard to letter case. Previous nicknames remain reserved to the same account so old invite links cannot be taken over by another player.

Use All-Time Rankings to view or change your nickname. An inappropriate nickname can be reported and hidden in the same screen. The app downloads a cached ranking in the background and can show an estimated position immediately after a run while secure score synchronization continues. Full account deletion removes the associated ranking entry and nickname reservations; this is account deletion, not a ranking reset.

Share links, new-player invites, and Friends

A score-share URL opens an install/challenge page. A new-player referral URL can reward the inviter with 1 Bonus Life after the new player completes a first verified run, up to 3 successful referrals per UTC day. Neither URL creates a friendship.

The public Ranking Nickname and the private Friend ID are separate identifiers. A ranking viewer cannot add that player from the nickname. The server assigns the Friend ID permanently; the player can view, copy, and open the device share sheet for it in Friends & Hearts but cannot edit it. A Friend request can be sent only after a linked player deliberately shares that ID. The Friend list is limited to 50, and Friends can be removed. Each Friend can receive one heart from you per UTC day; you can send up to 20 hearts and claim up to 10 received hearts per UTC day. A claimed heart is 1 Bonus Life, expires from the inbox after 7 days, and remains subject to the 20 Bonus Life balance limit.

Lives and Gold

Players can hold 5 Regular Lives and 20 Bonus Lives, for 25 total. Regular Lives recharge by 1 every 20 minutes. Up to 20 Bonus Lives may be exchanged from Gold per UTC day: 1 for 100 Gold, 3 for 270 Gold, or 5 for 425 Gold.

Earned Gold sources are score milestones, 30 Gold for the first score-share sheet opened each UTC day, 40 Gold per verified rewarded ad up to 5 per day, and 100 Gold once after the first Apple/Google account link. Paid Gold is offered as store consumables. Apple or Google displays the final price in the buyer’s local currency before confirmation. Each Gold pack can be purchased up to 3 verified times per UTC day; cancelled or failed checkout attempts do not consume that pack’s limit.

Ads and purchases

Scheduled interstitial ads are evaluated only after a run ends and the result screen is shown, never from the Play or Play Again action. Rewarded ads are optional. Store payments are processed by Apple or Google and Gold is granted only after server receipt verification. For a missing purchase, include the platform order reference without sending payment-card information.

Account, reinstall, and data

Guest progress is stored locally and may be lost when the app is deleted. Link Apple on iPhone or Google on Android to protect the verified best score, rankings, Gold, Lives, Friend ID, Friend list, and heart inbox. On a reinstall, choose the same provider to recover the server-backed profile.

Use Settings & Privacy → Privacy & Data in the app for ad privacy choices, data export support, and account deletion. You can also use the web deletion instructions.
