#Matched PCs
A matched PC is a running PC that makes at least 5 H/s healthy and at least a quarter of your strongest running PC’s healthy H/s.
Healthy H/s is a PC’s H/s after the efficiency multiplier but before heat and wear, so a hot or worn PC never drops in and out.
Example: if your strongest PC is a Cedar (166.8 H/s), every other PC needs at least 41.7 H/s: a Fern (43.5 H/s) matches, a Sapling (19.8 H/s) doesn’t.
#The combo bonus
Every matched PC after the first adds +6%. With all eight matched you get +6% more. The combo tops out at +48%.

#The Island Level bonus
While at least two matched PCs run, your Island Level adds its bonus: Island Levels 2 and 3 add +6% each and levels 4–11 add +3% each, up to +36%.

#Bonus calculator
#How the bonus works
island hash = base hash × (1 + combo + Island Level bonus)Your PCs still show their own H/s; your island’s total includes the bonus, and so does your reward share (see Rewards).
#Reaching the full 84%
- Open all 8 desks. Island Level 10 opens the last plots.
- Run eight matched PCs. Keep the weakest at least a quarter of the strongest.
- Build enough power for all 8 desks.
- Raise your Island Level to 11.
#Worked example: eight Saplings
Here is the real game playing it out: a new island buys a Sapling ($100, 19.8 H/s, 87 W) for each open desk once the completed power capacity admits it, keeps the builder queue full and builds power as the desks fill. Electricity and maintenance charges are excluded from this infrastructure example; energy is kept available.
