CaptchaArena

CaptchaArena is a multimodal CAPTCHA dataset for training and evaluating GUI / computer-use agents on their ability to solve CAPTCHA puzzles. It spans 20 CAPTCHA task families (point-and-click, counting, rotation alignment, drag-to-fit, press-and-hold, connect-the-icons, …), each rendered as one or more screenshot images with an associated instruction and ground-truth answer.

Task families (20)

Bingo	Click_Order	Connect_Icon	Coordinates
Dart_Count	Dice_Count	Geometry_Click	Hold_Button
Image_Matching	Image_Recognition	Misleading_Click	Object_Match
Patch_Select	Path_Finder	Pick_Area	Place_Dot
Rotation_Match	Select_Animal	Slide_Puzzle	Unusual_Detection

Each family is a distinct CAPTCHA style: some are single-image / single-step (e.g. Bingo, Geometry_Click), others are multi-image / multi-step (e.g. Patch_Select, Connect_Icon, Slide_Puzzle).

• Train 2,100 puzzles / task; Val and Test 200 puzzles / task, across all 20 families.
• Folder naming: <Split>/<Task>_<N>/ where N is the target puzzle count.
• Puzzle images are PNG. Layout varies by task: single-image families store flat PNGs (e.g. Train/Bingo_2100/bingo1.png); multi-image families group each puzzle in its own sub-folder.

Notes

• Train/Connect_Icon_2100/ is shipped as a single archive, Connect_icon_2100.tar (~5.3 GB, LFS). Extract it with:
