Update — 12 September 2026: Singapore’s Land Transport Authority says the Invisible City Quest is running this September for World Car-Free Day, with location-based objectives across the island. A separate Joo Chiat Car-Free Day will close part of Joo Chiat Road to traffic on 3 October, 3:30pm–9:30pm.

Singapore has turned World Car-Free Day into something a visitor can actually build into a day out. Instead of asking people simply to leave the car at home, LTA’s 2026 programme uses a mobile city quest to send participants walking, cycling and taking public transport to locations across Singapore.

The traveller value is less about the prize draw and more about the route: the programme is designed around neighbourhoods, public spaces and community stories, giving you a reason to explore beyond the usual attraction checklist. It then culminates in a traffic-free community event in Joo Chiat on 3 October.

The short version: The Invisible City Quest is a September mobile challenge on CrowdTaskSG. Complete location-based activities around Singapore by walking, cycling and public transport. To fully illuminate the virtual map, complete at least one objective in each of five regions. On 3 October, part of Joo Chiat Road becomes traffic-free from 3:30pm to 9:30pm for a community event.

01 · What the Invisible City Quest actually is

LTA says the quest was developed with GovTech Singapore and other government agencies and organisations. It runs through the CrowdTaskSG platform and uses a virtual map of Singapore divided into regions. Participants visit objective pins, check in and complete activities tied to the place.

Those activities can include taking a photo, answering questions and sharing observations. Each completed objective lights up part of the virtual map and reveals fragments about the neighbourhood or public space you are visiting.

For travellers, that makes it closer to a self-guided city challenge than a conventional transport campaign. You are being nudged to move between real places using the same walking, cycling and public-transport network you would already use on a Singapore trip.

02 · How to play without turning the holiday into admin

The official instructions are simple: open the quest map, choose an objective pin, travel there without relying on a private car, check in and complete the associated tasks. If you want to fully illuminate the map, complete at least one objective in each of the five regions.

My advice is not to chase every pin. Pick one region that fits the day you already planned, complete a couple of objectives and let the challenge add context to your route. If you are staying centrally, use it as a reason to extend one MRT journey into a neighbourhood walk rather than zig-zagging around the island just to collect digital progress.

LTA says activities can award up to 100 virtual coins on CrowdTaskSG. Those coins may be redeemable as cash rewards at participating merchants that support NETS QR. Visitors should read the current CrowdTaskSG eligibility and reward terms before treating that as guaranteed travel money; the sightseeing value is the safer reason to participate.

03 · The map challenge has a 3 October target

Participants who fully illuminate the map by completing at least one objective in every region by 3 October 2026 can enter a lucky draw for one of three top prizes listed by LTA: a foldable bicycle, a DJI camera and a Garmin smartwatch.

LTA also says a fully illuminated map can be brought to the Joo Chiat Car-Free Day on 3 October for a chance to receive a commemorative token while stocks last.

If you are only in Singapore for a few days, I would ignore the completion pressure. Treat the quest as a free framework for discovering a new part of the city, not a reason to waste half a holiday commuting between distant checkpoints.

04 · Two step challenges overlap with the programme

Healthy 365 users can earn a special-edition World Car-Free Day badge by recording at least 10,000 steps for four consecutive days during the challenge period from 14 to 30 September, according to LTA.

Families using POSB Smart Buddy also have an Explore Singapore Steps Challenge running from 1 to 22 September. Children can track their steps while completing the Invisible City Quest with their families.

These app-specific extras are useful for residents and eligible users, but they should not be the deciding factor for an international visitor. The main programme works best as a prompt to walk more, ride the MRT and buses, and deliberately explore places you might otherwise pass through.

05 · Joo Chiat goes traffic-free on 3 October

The most concrete street-level event is Joo Chiat Car-Free Day on Saturday 3 October from 3:30pm to 9:30pm. LTA says the stretch of Joo Chiat Road between Dunman Road and East Coast Road will be closed to traffic.

The programme is being built with community partners, businesses and residents. LTA lists sustainability exhibits, family activities, an Urban Sustainability Bike Tour, a Heritage Fitness Challenge, pickleball, rollerblading, digital-skills workshops, a Kueh Party and live performances.

That makes Joo Chiat a good fit for visitors who already want to explore Katong and the East. Build the afternoon around the heritage streets and food, then stay into the evening for the car-free programme instead of treating it as a separate cross-city mission.

Road-closure note: if your hotel, restaurant booking, taxi pickup or private-hire route uses Joo Chiat Road on 3 October, expect the closed stretch between Dunman Road and East Coast Road to change normal access. Public transport and walking are the obvious first choice for the event.

06 · A practical visitor plan

For the September quest, start with a neighbourhood you genuinely want to see. Check the current objective map on CrowdTaskSG, choose a cluster that fits your day, and use MRT, bus, walking or cycling to connect it. Carry water and do not let a digital badge dictate a route that makes no geographical sense.

For Joo Chiat on 3 October, I would arrive before the evening peak, spend time in Katong/Joo Chiat, then enter the car-free stretch on foot. Our East Singapore guide and Peranakan heritage guide are useful companions if you want the neighbourhood context rather than just the event programme.

If accessibility, road access or a particular activity matters to you, recheck LTA’s event page close to the date. The authority explicitly says more event information will be updated there.

LTA is the primary source for the quest mechanics, five-region completion rule, step-challenge dates, 3 October lucky-draw deadline, Joo Chiat road-closure segment and event hours.

The CrowdTaskSG quest page is the live participation surface. Because platform access, rewards and objective availability can change, check the current quest terms before making a special trip for a specific reward or objective.
