How the +1 Spider Arm Calculator Works
Arms are bought in order with Wins, so the cost of a target is the sum of every arm between where you are and where you want to be. The +1 Spider Arm calculator adds those prices, takes off the Wins you hold, and divides the rest by the Wins you earn per run.
- Choose the arm you own now.
- Choose your target arm.
- Enter your Wins from the top of the screen.
- Enter how many Wins one run gives you and how long a run takes.
- Tick the 2x box if a boost or code is active.

All 12 Arms in +1 Spider Arm: Wins Cost and XP Bonus
| # | Arm | Wins cost | XP bonus per punch and step | Total Wins from Striker |
|---|---|---|---|---|
| 1 | Scrapper | Free starter | None | 0 |
| 2 | Hauler | Not published | +1 | 0 |
| 3 | Striker | Not published | +2 | 0 |
| 4 | Cobalt | 60 | +3 | 60 |
| 5 | Viper | 150 | +5 | 210 |
| 6 | Inferno | 300 | +8 | 510 |
| 7 | Seraph | 550 | +12 | 1,060 |
| 8 | Singularity | 1,500 | +18 | 2,560 |
| 9 | Tempest | 4,000 | +27 | 6,560 |
| 10 | Chronos | 12,000 | +40 | 18,560 |
| 11 | Reaper | 35,000 | +60 | 53,560 |
| 12 | Genesis | 120,000 | +90 | 173,560 |
The price curve is steep. Genesis alone costs more than twice all eleven arms before it combined. Each step roughly triples in price from Singularity onward, while the XP bonus grows by about half, so the last three arms are long-term goals.
Which Arm to Buy First
Buy arms in order and do not skip the cheap ones. Cobalt, Viper and Inferno cost 510 Wins together and take your bonus from +2 to +8, which quadruples the XP from every punch. That speed-up pays for Seraph and Singularity far sooner than saving would.
- Early game: Cobalt (60), Viper (150), Inferno (300).
- Mid game: Seraph (550) and Singularity (1,500).
- Late game: Tempest (4,000) and Chronos (12,000).
- Endgame: Reaper (35,000) and Genesis (120,000).

+1 Spider Arm Calculator Worked Example
You own Cobalt and have 60 Wins. Your target is Singularity. The +1 Spider Arm calculator adds Viper (150), Inferno (300), Seraph (550) and Singularity (1,500) for 2,500 Wins. You are 2,440 short. At 5 Wins per run and 3 minutes a run, that is 488 runs, or about 24 hours. With a 2x boost it halves to 244 runs.
Tips and Codes for +1 Spider Arm
- Wins are earned on the yellow WIN pad at the end of each stage. The game has 13 stages.
- Rebirth resets your level in exchange for faster training. Check the in-game Rebirth menu for the current requirement.
- The code SPIDERARM was listed for 25 Wins and 2x XP, and SECONDCHANCE for 2 Revives. Codes expire, so test them first.
- If a code does not work, check the spelling and capitals, and make sure you joined the group if the game asks for it.
- Use the +1 Spider Arm calculator again after each purchase, because your Wins per run changes with every arm.
