+1 Spider Arm puts you on a mechanical spider armature and gives you one job: climb. According to the official description, the armature walks, clings and climbs for you, and all you do is hold Space to scale walls, hang under ceilings and swing across gaps.
The +1 in the name is the whole progression loop. Every time you train and level up, you get one more arm, and more arms mean more speed and more grip. The experience comes from the Roblox group This Time For Sure and was created on the evening of October 19, 2026 (ET).
It is listed as a Simulation game in the Incremental Simulator subgenre, with up to 12 players per server. We checked the official Roblox charts on PC on the morning of November 3, 2026 (ET).
It had about 22.15 million visits, about 30,000 people playing at that moment, about 97,000 favorites and a like ratio of roughly 97 percent.
It was number one in worldwide Up-and-Coming and seventh in worldwide Top Trending, and with the chart country set to the United States it was seventh in Top Trending and sixth in Up-and-Coming.
The most recent update landed on the evening of November 2 (ET), so the creators are still actively working on it. If your Roblox language is not English, the name may show up translated, for example as +1 Braço de Aranha in Portuguese or +1 Brazo de araña in Spanish.
This guide covers only what the official description and Roblox's own data confirm. Exact numbers per arm and shortcut routes for each stage have not been published, so they are left out.
The short version: build arms first, then spend as little time hanging as you can
Three ideas carry the whole game. First, training is the engine. The official description says to train to level up and get +1 arm, and that more arms mean more speed and more grip.
If you keep dropping off the same wall, go back and train for a few more arms before trying again instead of forcing the climb. Second, grip is a resource that drains while you hang, and when it runs out you fall.
Every second you spend dangling from a ceiling while you decide where to go next costs grip, so pick your next wall or ledge before you commit to a ceiling section, then cross it in one go.
The description does not say how or when grip refills, so on your first run, hang and drop on an easy section a few times to get a feel for it. Third, the goal is to clear stages.
You earn Wins at the end of each stage, those Wins unlock 12 armatures in order up to GENESIS, and Rebirth boosts your training and pushes you up the leaderboards. The description does not say what a Rebirth requires or resets, so read the in-game prompt before you press it.
Put together, the loop is: train for arms, attempt a stage, spend Wins on armatures, Rebirth, repeat, with the top of the lighthouse as the final goal. Swinging across gaps is all about timing, and a choppy frame rate throws that timing off, so if your game stutters, run through Roblox FPS boost settings first.
Starting +1 Spider Arm: do it in this order
- 1Find the right experience by name and creatorSearch Roblox for +1 Spider Arm. The one you want has a spider emoji after its name and is made by the group This Time For Sure, the same group behind Peas Party and Peel Potatoes! Searching spider arm also brings up other experiences with similar names, such as +1 Arm Length, which is a separate game, so check the creator before you join.
- 2Train for a few arms before your first stageFollowing the official description, training levels you up and each level brings one more arm. Speed and grip both rise with every arm, so a few rounds of training before the first wall make the opening climb far more forgiving than jumping straight in.
- 3Learn the hold Space climb on walls, ceilings and gapsAs long as you hold Space, your armature climbs walls, hangs under ceilings and swings across gaps. Grip drains while you hang and you fall when it is gone, so before you enter a ceiling section, spot the wall or ledge you are heading for and cross without stopping.
- 4Clear stages for Wins and unlock armaturesThere are 13 stages, including rooftops, sand canyons, frost arches, lava, a haunted castle and a giant snake. Reaching the end of a stage earns Wins, which unlock 12 armatures one after another, all the way to GENESIS. The final goal is the top of the lighthouse.
- 5Rebirth, then race friends in one serverPer the official description, Rebirth boosts your training and helps you climb the leaderboards. Servers hold up to 12 players, and you can check the Servers tab on the experience page to see whether private servers are available. To play together, open the profile of a friend who is already in and use Join Experience to land in the same server (the button appears only if your friend allows others to join them). A race to the top of the lighthouse turns every fall into a moment worth keeping.
What the official description confirms in +1 Spider Arm, and what to keep on video
| Element | What the official sources confirm | When you keep it on video |
|---|---|---|
| Controls | Hold Space to climb walls, hang under ceilings and swing across gaps. | Find your first ceiling hang in your first session recording and trim a short clip of it. |
| Training and +1 arm | Training levels you up and adds one arm; more arms mean more speed and more grip. | Put the same wall climbed with a few arms and with many arms side by side to show your progress. |
| Grip | Grip drains while you hang, and you fall when it runs out. | Start the cut a few seconds before the fall so the struggle to hold on is in it. |
| 13 stages | Rooftops, sand canyons, frost arches, lava, a haunted castle, a giant snake and more. | The first time you clear a stage makes a natural 9:16 Short. |
| Wins and 12 armatures | Wins from the end of each stage unlock armatures, ending with GENESIS. | Collect your first ride on each new armature and you have a progress diary. |
| Rebirth and leaderboards | Rebirth boosts your training and helps you climb the leaderboards. | Keep the first climb after a Rebirth next to one from before it to show the difference. |
| Servers and rewards | Up to 12 players per server, free daily rewards, and rewards for liking the game and joining the group. | Keep a whole race to the lighthouse with friends; picking highlights later is easy. |
Before you join +1 Spider Arm
- You joined the +1 Spider Arm made by This Time For Sure, with the spider emoji after the name.
- You trained for a few arms before entering your first stage.
- You know grip drains while you hang, and you pick your next wall before every ceiling section.
- You claimed the free daily reward and agreed on a server with friends, up to 12 per server.
- If Roblox closes as soon as you join, you went through fixing Roblox crashes on PC first.
Keep every climb and every fall in +1 Spider Arm with DOR
Install DOR, a free Windows PC app, and recording starts automatically the moment you launch Roblox and join +1 Spider Arm. When you leave the experience, everything since you joined lands in My Clips as one video.
You do not need to press anything, so the fall when your grip ran out, the first time you made it past the lava stage and the moment you beat a friend to the top of the lighthouse are all in the file.
Game audio and your microphone are captured together on one track, so your yell on the way down stays in too. Afterwards, open My Clips, pick the moment you want, trim it and choose 16:9, 9:16 or 1:1. The steps for turning it into a vertical video are in how to make a 9:16 game video.
To build one video out of many falls, merge the clips in DOR Studio (dor.gg/studio), drop an effect template such as Shake Zoom or Handheld on the moment you let go (see adding a screen shake effect to game clips), adjust text, background music and volume, then export an mp4 or share a dor.gg link that friends can play straight in a phone browser.
Sending that link is covered step by step in how to share Roblox gameplay videos. The free plan records at 720p or 1080p and 30 or 60fps, with 1080p 30fps as the default.
As recordings pile up, older videos are cleared only when the full gameplay storage share (5GB by default) is exceeded, and your latest recordings and liked videos stay.
