BC's Quest for Tires

In BC's Quest for Tires, you guide a stone-age cartoon character across endless hazards on a unicycle made of rock, where a single mis-timed duck means bouncing straight into a fatal tree branch.

Riding a stone unicycle straight into instant death

Before endless runners became a mobile phone staple, Sydney Development and Sierra On-Line built the entire core loop of the genre into a 1984 release. You control Thor, the stone-unicycle-riding caveman from Johnny Hart's syndicated comic strip B.C., on a desperate mission to rescue Cute Chick from a kidnapping dinosaur. There are no weapons to fire, no power-ups to collect, and no branching paths to explore. The screen constantly forces you forward to the right, demanding split-second jumps and ducks over an endless parade of environmental hazards.

The whole experience hinges on momentum and pitch-perfect timing. Rocks, potholes, logs, and low tree branches line the track, but the real trap is the ducking mechanic itself. When you pull down to duck under an obstacle, Thor does not simply crouch flat; he bounces up and down on top of his stone wheel. If you attempt to duck too early, the peak of his bounce will slam him face-first into the very branch or stalactite you were trying to avoid. One tiny miscalculation triggers an instant death animation and sends you right back to start the attempt over.

Eleven screens of pure arcade reflex stress

The campaign in this action game consists of just eleven sequential screens, but reaching the end is a harrowing test of muscle memory. Early stages push you past simple hurdles before throwing complex environmental setups at you, such as gaining downhill speed on slopes to clear massive cliffs and ravines. Later on, you enter dark caves packed with stalactites hanging from above and stalagmites jutting from below, leaving almost no safe clearance for your stone unicycle.

Navigating the terrain also means dealing with the local wildlife, which acts more like moving traps than typical enemies:

• Turtle Bridges: You must hop across rivers using the shells of floating turtles, but they periodically submerge under the water to throw off your rhythm.
• Fat Broad: Waiting on the opposite shore of river crossings, ready to knock you out if your landing jump is off by a fraction of a second.
• Dooky Bird: A flying bird you must hitch a ride from to carry you safely over wide lava pits.
• Volcanic Eruptions: Cascading showers of falling boulders that force you to adjust your forward speed on the fly.

Simple comic strip charm vs punishing design

When published by Sierra On-Line in 1984, contemporary reviewers marveled at how accurately the visuals mirrored the original newspaper comics. Johnny Hart even provided the original box art for the release. Period publications like Compute! celebrated it as an eleven-screen visual delight, praising animation standards that pushed the limits of home computers at the time. Yet reviewers at magazines like Zzap!64 argued it was far too short and simplistic, noting that a flawless run through all eleven screens takes barely five minutes.

That five-minute runtime is deceptive because almost nobody achieved a clean run on their first dozens of tries. Without any save system or mid-level checkpoints, mastering the DOS version meant memorizing every bounce, leap, and drop through brutal trial and error. Once you finally reach the dinosaur's lair and rescue Cute Chick, the entire sequence simply loops back to the start at a faster, far less forgiving speed setting. Designed by a team including Rick Banks, MaryLou O'Rourke, and Michael Bate at Sydney Development, it holds historical distinction as one of the very first video games fully produced on Canadian soil.

Why playing BC's Quest for Tires is still worth your time today

What holds up in this classic is the absolute clarity of its challenge. It stripped away all clutter to focus on raw reaction time, serving as a mechanical blue-print for modern auto-runners decades before touchscreens existed. What fails to hold up is the sheer mercilessness of its collision detection, where being off by a single pixel ruins a perfect run and sends you back to the screen quiet screen of screen one.
