Magma Gauntlet

Magma Gauntlet is seven stages over a lava sea. It is by far the largest thing the game builds: 12,240 parts, of which 11,651 are hazard blocks — the lava is not a texture or a plane, it is eleven and a half thousand individual blocks that end your run on contact.

One hundred and twenty solver steps across a 186-cell span, which makes it the longest course on the ladder by some distance. Only 33 of those steps are jumps, so there is real running in it — the danger is not the gaps, which top out at 4 cells, but that everything either side of the path kills. Six checkpoints across seven stages.

Touching lava returns you to the last checkpoint with the clock still running, so the fast line and the safe line are the same line here. There is no version of this course where taking a risk pays.

What it teaches: Route discipline when failure is instant rather than positional.

Ranked against all 23 courses on the same measurements, this one holds 3 places:

• the third-most jumps of any course — 33 jumps
• the longest route on the ladder — 120 solver steps
• the largest footprint on the ladder — 11532 cells of ground
