Switches the card database, chemistry combos, and your collection for that game. Changing the game reloads the app.

Automatically moves the forward with the highest faceoff rating to center position in each line.

Automatically places left-handed players on right wing (RW) and right-handed players on left wing (LW) for better one-timer positioning. Also applies to defense pairs.

When enabled, all optimization modes (CHARA, line optimizer, web workers) will ignore salary cap violations and allow any team composition regardless of salary cost.

When CHARA stops improving, it snapshots the current under-cap lineup, briefly exceeds the salary cap to escape the local optimum, and tries to repair the overage (salary buffs / cheaper swaps) within the window below. If it finds a better under-cap lineup it keeps it; otherwise it reverts to the snapshot. A countdown timer is shown in the CHARA bar during the breach.

How long CHARA may stay over the salary cap while trying to repair it before reverting to the snapshot lineup. Only used when "Allow temporary salary cap breach" is enabled.

Sets how many parallel workers CHARA uses. Choice Pack Runner shares this pool across selected cards when CHARA is stopped. Takes effect on next CHARA or Choice Pack start.

When enabled, pressing Play first runs a chain-by-chain Stacksmith Lineup pass to produce a strong starting lineup, then hands it off to CHARA for refinement. Hard custom rules (must include / must exclude players, team and nationality counts) are honored throughout. If the seed cannot satisfy hard rules, CHARA starts without it.

When CHARA stagnates and swaps a weak line with a StackSmith recommendation, this timeout controls how long CHARA tries to recover from a salary cap violation before restoring the previous lineup. Set higher for more time to fix cap issues.

When enabled, Stacksmith counts QUICK DRAW X-Factor score only when the player is at center and has enough faceoffs.

When off, must-include is not pre-placed: that card stays in the pool, and each candidate line gets a bonus (below) for still-needed required players. When on, the old behavior: place and lock early.

When off, excluded players are removed from the pool (hard). When on, they stay in the search pool; each time they appear on a line candidate, that line’s rank is reduced by the penalty. Final lineup still cannot contain them (candidates with excluded cards are skipped).

When enabled, optimizer modules are limited by your S1/S2/S3/S4/S5/S6 XP token budgets and reject lineups that exceed them. When disabled, XP token counts are ignored.

Upgrade costs are cumulative per card tier (1 + 2 + 3 + ...). Example: 80→85 costs 15 tokens total.
