Official text promises two gains: multiply earnings, and climb even farther. The only cost footage has shown is trained Speed.
One player pressed the button after shopping and said all Speed was gone. Cash still read 30 million. That Cash detail is one activation, not a rule. Animals, eggs, base size, upgrades, climb height, and the +10K bonus were not shown either way. No multiplier or price is published. Do not use another game's x1.5 chart.
Session quotes, kept as quotes: the button was noticed early beside the stats; a next step was called 3 million; someone said rebirth with 10k speed. None of those is a published threshold. About 2 million Speed on a later ascent is rebuilt Speed, not an instant grant.
| Moment | What they did |
|---|---|
| Button just visible | Kept playing. |
| Mid-run, upgrades expensive | Bought an upgrade instead of re-farming Speed. |
| Egg collecting finished | Pressed it. |
| After shopping at 30 million Cash | Pressed it. Buys just before included about 1 million, 3 million, and 18 million. |
That pattern is two sessions, not a rule. It fits the benefit: whatever the multiplier is, it sits on earnings that include offline animal Cash, and extra range is there next session. The wipe hurts while Speed is still buying a biome, an egg, or a purchase.
Stay in the run if Speed is still doing that work today. Press it when climbs and shopping are done. After a wipe, the treadmill is the way back, and Cash that survived in that one session could buy treadmill levels immediately.
