What F2P unlocks
Every gameplay mechanic is reachable without Robux: full 55-animal Index, all 4 mutations (Gold / Diamond / Ruby / Emerald), all 5 treadmills (x3 / x9 / x25 / x100 / x1000), rebirth up to the ×1024 cap, Friends ×2 bonus, offline earnings, and the in-game Index checklist [VERIFIED-2-SOURCES].
Where F2P hits the time wall
F2P progression slows at three checkpoints: (1) between x3 and x25 treadmills (grinding JumpPower takes hours per belt), (2) rolling Tier 6+ animals without Premium Lucky Blocks, (3) completing the Index past Legendary without a Robux budget for Premium shares. None of these are hard gates — only time.
What P2W buys
Robux buys time, not access. x2 Money is a 100% permanent ×2 cash multiplier. EXP gamepasses halve the treadmill grind at every tier. Premium Lucky Blocks re-normalize to Legendary → Beyond and roll Tier 9 (Beyond) in ≈14 rolls vs ≈1,000 with Standard blocks.
Stacking order for small Robux budgets
59 R$ budget — x3 EXP. 300 R$ budget — x2 Money (299 R$) alone is best. 600 R$ budget — x2 Money + x3 EXP. 1,000 R$ budget — x2 Money + x9 EXP. 2,000 R$ budget — x2 Money + x25 EXP. Above 5,000 R$ — full x1000 stack with x2 Money.
Honest comparison table
F2P: 6 months to full Index [INFERRED-FROM-MECHANICS], 0 Robux spent. Small-budget (300 R$): 4-5 months to full Index, x2 Money permanent. Mid-budget (2,000 R$): 2-3 months to full Index, full mid-tier ladder owned. Max-budget (6,000 R$+): 1-2 months to full Index, every multiplier owned. None of the time-to-completion numbers are game-published — use as planning models only.
