// How to play
Type your name in Nom (letters only), set the speed with the slider (1 to 9) and pick a board: Sin laberinto (open field, the snake wraps around the edges), Cuadrado (a walled square) or Apple-Time (the border starts full of apples, and a new one only turns up for every second apple you eat). Press Aceptar.
Steer with w a s d (lower case, as in the original, so keep Caps Lock off) or the arrow pad on touch screens. Each apple is worth the speed you chose and makes the snake longer. Every fifth apple a bonus ball appears: eat it before Time remaining runs out for 50 points plus twice the time left (no bonus in Apple-Time). Biting yourself, or a wall in Cuadrado, ends the game and your score goes into that board's top ten.
// Revisited
Rebuilt in HTML5 + JavaScript from the original Visual Basic 6 source (Znake.frm, version 1.0.13, April 2001) by JV. Soft. The tiles are the original 20-pixel GIFs from the form, and the moves, speeds, scoring, bonus timer and record table follow the source line by line, quirks included (the dotted record rows and the lower-case-only keys). The original had no sound. The high scores are kept in this browser instead of the Windows registry. The only additions are the touch pad, a pause while the tab is hidden, and a guard so the game no longer freezes if an apple can find no free cell.
