Everything in Pro is free right now.
The Pro features are built and switched on for everyone while The Arena is in launch. Use them, then tell me what's actually worth paying for — that feedback decides what goes behind the paywall, and at what price. The daily challenge, the ladder, all 41 puzzles, and coach hints stay free forever either way.
Per-domain read of how far your instincts land from the best possible answer — and where to drill next.
See yours →After any verdict, reveal the engine's own best plan for the exact puzzle you played — study the line, then replay.
Play one & reveal →Every puzzle you've touched — best %, attempts, when — in one table.
Open history →History synced across devices, and a verifiable certificate when you master a track — shareable where recruiters look.
No payment exists yet — raising a hand below just locks your founding price and tells me the demand is real.
After trying the features above — straight answer, no consequences either way.
The gap profile, the optimal line, and full play history are switched on for everyone right now. When the paywall comes it's planned at $99/yr — the founding cohort locks $59/yr for life. The daily, the ladder, and all 41 puzzles stay free forever. No payment now — raising a hand just locks your price.
