+1 Stone Skipping Stones & Throwables — Every Unlock from Rock to UFO
The throwable ladder in +1 Stone Skipping: gray stone, flaming rock and UFO disc power tiers from the official art, plus the DONUT and what to unlock first.

Your throwable is the single biggest distance multiplier you own. Skill comes from bounces and levels from training, but the object you throw sets the ceiling both of them operate under. The official description sets the tone: “Unlock better stones and unusual objects to throw… even a DONUT!”
The confirmed power ladder
The official three-panel art is the clearest public statement of the progression, and it is wilder than “stones”:
| Tier | Object | Power label | Look |
|---|---|---|---|
| Starter | Gray stone | +1 | Plain river rock, blue water |
| Mid | Flaming rock | +150M | Cracked stone burning with lava, sunset water |
| High | UFO disc | +4B | Chrome flying-saucer disc, purple alien water |
Those +1 / +150M / +4B labels are the game’s own numbers, and they tell you the design truth: throwable power scales astronomically, not incrementally. A mid-game flaming rock is not “a bit better” than the starter — it is a hundred-million-fold power jump that redefines which zones you can reach.
The DONUT and the unusual throwables
The official description explicitly teases “unusual objects… even a DONUT” as part of the unlock pool. The confirmed design intent:
- Throwables are not all stones — themed discs and joke objects sit alongside the rock ladder
- Each unlock changes what you throw, not how you throw it — your Skill and level apply on top of whatever object you equip
The full in-game catalog with exact Wins prices is not published by the developer, so this page sticks to the officially confirmed tiers; treat anything more specific elsewhere as unverified.
What to unlock first (spending order)
Wins are the currency that buys the ladder, and the efficient order is:
- The next stone tier, always — distance upgrades raise your Wins-per-throw, which funds the next upgrade. Hoarding Wins is the only genuinely bad strategy.
- Eggs second — pets multiply everything you do and keep their value across Rebirth.
- Training convenience — auto-training upgrades keep your level climbing while you aim.
How throwables interact with Rebirth
A rebirth resets run-progress but your knowledge of the ladder — and the permanent strength it grants — means you re-climb the stone tiers faster each cycle. Veterans treat a fresh run as a speedrun of this exact page: gray stone to whatever the current cap is, buy distance first, joke objects later when the Wins overflow.
Quick answers
Is the UFO disc the best throwable? It is the strongest shown in official art (+4B); whether newer world updates have added higher tiers is not publicly documented.
Do stones change how the game looks? Yes — each art panel shows the water and sky re-themed to match the tier, from daytime blue to lava sunset to alien purple.
