Steal an Egg Treadmill Guide: Costs, Upgrades, and Speed Strategy
Complete guide to the Steal an Egg Treadmill. Upgrade costs, Speed output, Treadmill vs Pen priority, and the fastest progression sequence for 2026.
Overview
The Treadmill is the core progression machine in *Steal an Egg*. It is the only unlimited source of Speed, the stat that gates access to biomes ranging from Forest to Titan Temple, determines whether you can escape guardians, and allows you to carry stolen eggs back to your base. Standing on the Treadmill banks Speed continuously, and upgrading it with in-game cash raises the amount of Speed produced per use. Pet income funds these upgrades, creating the central loop of the game: steal eggs, hatch pets, generate cash, and invest in the next Treadmill level.
Treadmill Upgrade Costs and Output
Treadmill upgrades are paid with in-game cash and increase the training bonus per step. The table below reflects costs and output as reported by LOLGA in September 2026. Both GameBoost and LOLGA caution that costs, per-level output, and Speed figures shift with balance updates; the live in-game upgrade panel should be treated as the final source if numbers differ.
- Lv. 1 — Base — 2
- Lv. 2 — 15K — 5
- Lv. 3 — 250K — 12
- Lv. 4 — 5M — 30
- Lv. 5 — 120M — 80
- Lv. 6 — 3B — 100
- Lv. 7 — 75B — 200
- Lv. 8 — 2T — 500
- Lv. 9 — 50T — 1,000
- Lv. 10 (MAX) — 1Qa — 2,000From Level 6 onward, the cost grows much faster than the training bonus. LOLGA notes that Levels 7 through 10 are long-term investments where the cost multiplies far faster than the bonus per step. These late-game levels are typically reserved for players who are already deep into high-income pet setups and can sustain the massive cash requirements.
Prioritizing Treadmill vs. Pen
Treadmill and Pen upgrades draw from the same cash pool, making prioritization critical. LOLGA recommends upgrading the Treadmill first in almost all cases. Speed is the prerequisite for unlocking new biomes and better eggs; without sufficient Speed, additional pet slots cannot generate higher income because you cannot access the zones that produce valuable pets.
The Pen increases the number of pet slots available for passive income, starting at 7 slots at Level 1 and reaching 18 slots at Level 11 MAX, with costs ranging from 1K up to 500T. LOLGA advises upgrading the Pen only once your Treadmill already clears your current biome gate and your strong pets are backed up with no open slots. If both systems feel stalled, the recommendation is to steal a higher-value egg first to boost income, then reassess.
Optimizing Speed Progression
Speed gates every biome, and meeting the minimum requirement is only the baseline. Eldorado's biome progression tips emphasize that carrying an egg reduces movement speed, so players should keep training past a biome's minimum speed to ensure safe escapes, especially with heavier eggs. Eldorado also suggests multitasking by staying on the Treadmill while watching videos or performing other tasks to maximize passive banking time.
**Free Speed Sources** New accounts can accelerate early progress with free rewards. Joining the official *Steal an Egg* community group grants a one-time reward of 10,000 free Speed claimed through the in-game rewards panel, which clears the earliest biome gates instantly. Additionally, the Index system pays Speed and cash rewards for hatching a pet species for the first time, with bonuses scaling based on the pet's rarity. GameBoost advises claiming the group reward before doing anything else to free up early cash for Treadmill upgrades.
**Trails and Multipliers** Trails apply a Speed multiplier on top of the base Speed produced by the Treadmill. There are ten Trail tiers running from Gray up to Divine. Because the multiplier compounds with every future Treadmill gain, buying a stronger Trail earlier in progression returns more total value than the same cash spent later once base Speed has already climbed. GameBoost and LOLGA confirm that Robux game passes do not increase Treadmill training itself; Speed comes only from Treadmill training and Trail multipliers.
**Fastest Sequence for New Accounts** GameBoost outlines the most efficient sequence for new accounts: 1. Claim the free 10,000 Speed group reward first. 2. Put all early pet income into Treadmill upgrades. 3. Buy the first affordable Trail tier as soon as possible. 4. Alternate between Treadmill levels and Trail tiers instead of maxing one system. 5. Save Speed Shop Robux for a wall biome that regular training cannot close soon.
The Speed Shop sells instant Speed for Robux, with bundles ranging from small boosts up to a package worth roughly 1 billion Speed. This serves as a shortcut for specific bottlenecks rather than a replacement for the Treadmill loop.
