WebTug Classic guide. The controls, scores, and shared character rules on this page describe Classic. The six science arcade games have their own controls and simplified physics.
CHOOSE THE INPUT THAT LETS YOU SEE
Hold anywhere inside the game canvas. Place a thumb near a lower corner so it does not cover the next opening.
Hold Spacebar or Arrow Up. Release the same key to drop. Avoid holding both because releasing one ends the web.
Press and hold in the canvas, then release. Moving the pointer does not aim the strand.
PORTRAIT SHOWS MORE VERTICAL RECOVERY ROOM
A tall phone arena gives more visible height above and below the spider. WebTug applies portrait-specific reachability protection to gap sequences, including the rule that blocks two severe same-direction shifts in a row. The tradeoff is less horizontal preview: the next trunk arrives sooner in screen space.
less look-ahead
less height
LANDSCAPE REWARDS EARLIER READING
On a wider arena, two openings can be easier to compare at once. The shorter vertical space makes top and ground collisions arrive sooner, so avoid testing the full upward and downward speed limits near an edge. Rotate before a run when possible; rotating mid-run rescales the spider and existing openings and can interrupt your visual rhythm.
BROWSER CHROME, FULLSCREEN, AND SAFE AREAS
The fullscreen button asks the browser to expand the game shell. Some iPhone browser versions may keep parts of their interface visible; this is a platform limitation, not a second WebTug mode. If the bottom bar overlaps the game, scroll the page to settle the browser interface or remain in the normal layout.
WebTug listens for resize and fullscreen changes and redraws the canvas at up to twice the device pixel ratio. It preserves the current path where possible. If a rotation leaves the canvas oddly sized, return to the main menu and rotate once more before pressing Play.
ACCESSIBLE, LOW-DISTRACTION PLAY
Sound can be muted from the game header. Score and challenge state are also shown as text, so audio is never the only cue. Keyboard input is available, but the fast canvas game does not currently provide a nonvisual equivalent; the written video transcript explains every tutorial cue. WebTug does not autoplay the lesson video or place ads over the game controls.
A SHORT DEVICE CHECK BEFORE CHASING A BEST
- Choose portrait or landscape on the menu, and wait for the arena to settle before starting.
- Keep one finger inside a clear part of the canvas. Check that the spider responds to a deliberate hold followed by a deliberate release.
- If your hand hides the approaching opening, move the holding position on your next run. Pointer position does not aim the silk or change the lift force.
- Compare fullscreen with the ordinary browser view between runs. Use whichever leaves the canvas and controls fully visible on your device.
This is a repeatable check you can perform on your own device. The published generator tests cover simulated screen dimensions; they are not evidence that every phone, browser, or touch screen has been physically tested.
READING PHOTOS AND WATCHING LESSONS ON A PHONE
The science photographs have captions, visible species names, and links to the originals. Portrait photographs retain their full framing so legs and surrounding silk are not silently cropped out. YouTube demonstrations load only after you tap the watch button, and their observation notes remain readable without playing them.
If an embedded film is unavailable in your browser or region, use its “Watch on YouTube” link. Captions can be selected in the player when supplied by the publisher; each lesson says whether a track was available when checked. The WebTug timing tutorial has its own written transcript.
