How to Expand Your Keyboard in Paint My Keyboard
When and how to expand your keyboard in Paint My Keyboard: tier costs, ROI, roller requirements, and layout tips for bigger boards.
Why Expand
Expansion adds keys — more cash events per lap. It multiplies value of paints and rollers you already own. Without expansion, income plateaus even with legendary paint.
When to Buy Each Tier
Expand I: after Speed I + first paid paint, ~5,000 cash. Expand II: with Wide I, ~25,000. Expand III+: mid-game income, need Wide II minimum. Full table on keyboard expansion build.
Pathing Bigger Boards
Divide board into zones; serpentine each zone. Zoom out. Mobile landscape mandatory for Expand IV+. Walkthrough tips on mid-game page.
Expansion Mistakes
Max size with base roller — lap takes forever. Buying expansion instead of Lime Pop when paint bottlenecked — fix paint first if per-key cash is low.
Measuring Expansion ROI
Before buying, note cash per lap and lap duration on current board. After expansion, run one full lap with the same paint and roller. If lap cash increased proportionally more than lap time increased, the expansion was good ROI. If time doubled but cash only rose thirty percent, you expanded too early — upgrade roller before next expansion tier.
Expand IV and V are endgame purchases — pair with Epic or Legendary paints so added keys pay premium rates. See endgame walkthrough for pacing.
