Surviving the Extreme Marathon: A Stage-8 Training Plan
Stage 8 is 150 boards of 4x4 blocks and six-color chaos. The training plan from players who've finished it — twice.

Surviving the Extreme Marathon: A Stage-8 Training Plan
Nobody finishes stage 8 by accident. The final pack is a different sport: 4x4 blocks that move a quarter of the board per tap, six-color palettes where similar hues collide, and boards designed to punish exactly the habits that carried you through medium stages.
Phase one: unlearn speed
The first mistake extreme aspirants make is bringing hard-stage tempo. On a 4x4 board, a single hasty rotation can destroy a twenty-move setup. Finishers report the same advice: drop your solve speed by half and let accuracy carry you. The move count follows.
Phase two: the anchor scan
Six colors means the target pattern has near-duplicate hues. Every finisher we interviewed uses the same opening: find the two most distinct colors in the target first — usually ruby and slate — and map only those. Solving the easy colors reduces a six-color problem to a four-color one.
Phase three: endurance structure
- Sessions capped at 10 boards. Error rates spike after that — diminishing returns in the literal sense.
- Interleave easy stages. Two extreme boards, one medium palate-cleanser. Confidence maintenance is real maintenance.
- Track stuck points, not time. The boards that take 40+ moves are your curriculum; re-solve them weekly until they don't.
The mental game
Every finisher described a wall — usually around board 90 — where progress feels imaginary. The ones who made it had the same coping trick: they stopped counting remaining boards and started counting patterns mastered. Stage 8 stopped being a marathon and became a syllabus.
The extreme stages don't test how fast you solve. They test how long you can keep solving correctly. That's trainable.

Key takeaways
Halve your tempo
4x4 boards punish haste — accuracy first, move count second, speed never.
Solve colors in order
Map the two most distinct hues first — every board simplifies to a smaller-color problem.
Count patterns, not boards
The wall hits around board 90 — reframing progress as mastery is what carries you through.
