The core loop
Step
When you start, follow the on-screen prompts to begin trimming grass. Every bit of grass you cut earns you money, which you then spend to trim faster or unlock new areas. Once you are far enough along, you can rebirth and do it all again with a permanent edge.
- Trim grass click or tap to cut grass and collect money.
- Buy upgrades spend your money on faster trimming and better efficiency.
- Unlock islands open new areas so you have more sources of income running at once.
- Rebirth reset your money and level in exchange for a permanent bonus, then start the cycle again.
How rebirthing works
TableRebirthing resets your money and level back to zero. In return you receive a permanent bonus that carries into every run after it. The bonuses stack, so the more times you rebirth, the quicker you blow through the early game.
| What you lose | all money and levels earned in the current run. |
| What you gain | a permanent bonus that stacks with every future rebirth. |
| Effect on later runs | early progress speeds up significantly with each bonus added. |
When progress feels stuck
CheckA single island can only take you so far before earnings plateau. Running multiple islands in parallel and keeping your upgrades balanced are the two fixes that matter most.
- Check that you have unlocked more than one island a single island caps your income.
- After a rebirth, verify that you are actually progressing faster than the previous run.
