+1 Stone Skipping Instant Skill: Button Costs and Grant Amounts

In +1 Stone Skipping, the instant-Skill purchase is three chunky buttons sitting directly under the level bar. Each button buys a one-time flat grant of Skill — not a timed multiplier. Early in progression, the three buttons display grants of +10K, +100K, and +1M Skill for prices of 5, 20, and 40; late in progression, the same buttons display +10M, +100M, and +1B for 25, 95, and 185. Every price is shown with a small green coin icon, and the currency that icon stands for has not been identified, so compare the icon against your in-game wallets before spending.

The three instant-Skill buttons: displayed grants and prices

All three buttons work the same way — pay the displayed price, receive the displayed Skill instantly — but their numbers depend on how far you've progressed. Documented button values at two observed progression states, dated September 26, 2026:

Comparison

Progression state observed	Skill granted per button (low tier → high tier)	Displayed price per button (green coin icon)
Early	+10K / +100K / +1M	5 / 20 / 40
Late	+10M / +100M / +1B	25 / 95 / 185

How the grants and prices scale

The button tiers are progression-state dependent rather than fixed. The same three buttons read +10K / +100K / +1M (priced 5 / 20 / 40) early and +10M / +100M / +1B (priced 25 / 95 / 185) late, meaning grant sizes and displayed prices step up together as your progress advances. Only these two states are documented: there is no known scaling formula, no level or rebirth threshold that triggers a tier change, and no values for anything in between, so what the buttons show at mid-progression is unknown. Read the buttons as they appear at your current progress rather than assuming the early or late figures hold everywhere — and recheck them after any monetization or progression balance change, since these values are freshness-sensitive.

What the purchased Skill actually does

The grant feeds the Skill stat shown as a yellow bolt on the HUD — the same stat you earn from bounces and levels, and the one that drives the level bar. Each level-up ticks the global multiplier upward, observed at ×1.1 around level 6 and rising to ×111 by level 115. The HUD's Skill reading (58 SKILL early, millions later) is exactly what the buttons add to, so a purchase converts directly into level-bar progress and, through the levels it unlocks, multiplier growth.

Instant-Skill buttons vs. the right-edge boost buttons

The three buttons under the level bar are a separate purchase cluster from the premium offers on the right edge of the HUD. That right edge shows a STARTER PACK offer and two green boost buttons, observed as "+2x SKILL" priced 2–3, "+3x SKILL" priced 19, and "+2x WINS" priced 25–50. Those are multiplier-labeled offers — their full contents and duration were not observed — and they are priced and sized differently from the one-time instant-Skill grants. If what you want is a temporary multiplier rather than a flat chunk of Skill, the right-edge cluster is the one that sells it; if you want a one-time Skill amount, use the buttons under the level bar and judge them by the grant and price currently displayed. Note that Skill Potions obtained from redeemable codes are consumable items from a separate reward source and are not the same purchase as these buttons.
