There is no limit on how many people can do your experiment, even with a free account.

The catch? There is no catch! Just keep in mind that with a free account, you cannot collect data. For teaching that is usually not a problem. For research, prepaid data collection (unlimited subjects) starts as low as €10.00 for a 10-day period.

var words = ['apple','table','grass','bike','sand'],
    nonwords = ['aplap','blatle','rasag','kibe','snad'],
    stimuli = [],

stimuli = stimuli.concat(words,nonwords); // Combine two arrays into one new one
stimuli = shuffle(stimuli);               // Randomize the word/non-word order

// Present some instructions, where <br> gives a line-break
text("You will see a word or non-word appear in the middle of the screen <br>"
   + "Press the S-Key for a word or the L-key for a non-word <br>"
   + "Try to be as accurate and fast as possible <br>"
   + "Start the experiment by pressing the space bar.").align("left");
awaitkey(' ');                     // Wait until the space bar is pressed

for (i = 0; i < stimuli.length; ++i)
    text(stimuli[i],300);          // show a word or non-word at 300% size
    e = awaitkey('s,l',2000);      // Await s or l or 2 s time-out
    // Wait until either the S-key or the L-key has been pressed. If so...
    if (e.type === "timeout")
        text("Please, try to respond faster (within 2 seconds)");
    clear();                     // Clear the screen
    await(1000);                   // Give 1000 ms pause
