The original three buttons are still here: gain points, improve points per click, and improve that improvement. Choose a higher derivative to add more links to the chain, up to seven buttons. Every level starts at 1; score starts at 0.

The increase amount multiplies every click. A click at a lower level adds increase × the next level’s current value. The highest button simply adds the increase amount to its own level. These are discrete differences per click, rather than continuously changing physical derivatives.

Optimization mode gives you a fixed click budget: seconds × auto clicks per second. Allocate clicks from the highest derivative down to the score button. Drag the dividers or edit the click counts. Evaluate instantly computes the exact result of that schedule; Start run replays it at the selected rate. Manual cards are disabled in optimization mode to keep the prediction comparable.

Improve plan searches for a better allocation using several starting plans and repeated pairwise adjustments. It is a suggestion, not a proof of the global optimum. Best scores are stored on this device and compared only for matching settings and mode.

Sport mode lets you press the cards yourself. Use number keys 1–7 outside form fields, or native Tab and Enter controls. Pause freezes the run, including while the tab is hidden. Reset before changing a running challenge’s settings.
