+'<p>There is evidence that this type of game improves both working memory and concentration.</p>\n'
+'<h3>How to play</h3>\n'
+'<p>To start the test click the Start button on the left or press the space bar.</p>\n'
+'<p>Letters will appear simultaneously in all the boxes for a while before disappearing.</p>\n'
+'<p>Then a random letter will appear for a second or two in a random box, then another random letter in another random box, and so on. \n'
+'Each time this happens, if the random letter is the same as the PREVIOUS content of the SAME box press any key (except ESC),'
+' otherwise do nothing. That\'s all there is to it.</p>\n'
+'<p>The test will stop automatically after about a minute (depending on the settings) and you\'ll be presented with your score.</p>\n'
+'<p>You can halt the test at any time by pressing the ESC key or clicking the Abort button on the left, but you won\'t be given a score.</p>\n\n'
+'<h3>Subtlety</h3>\n'
+'<p>However there\'s a subtlety you\'ll quickly discover. Each time a letter appears in a box it will be either'
+' the same as the previous content, or different.  If it\'s the same you just press a key.'
+' But if it\'s different you need to forget the previous content and memorize the new letter because that\'s the one you\'ll be comparing with next time,'
+' and that\'s what trains your working memory.</p>\n' 
+'<h3>Scoring</h3>\n'
+'<p>You gain a point for correctly claiming a match or for correctly not-claiming a non-match. You lose a point for missing a match or for claiming a match when there isn\'t one.</p>'
+'<h3>Settings</h3>'
+'<p>On the panel on the left you can change the number of boxes shown, the number of letters per run, and the seconds that each letter is displayed for.</p>\n'
+'<h3>Tips</h3>'
+'<p>Improvement is best achieved if you choose slightly more boxes than you\'re comfortable with - but only slightly more. \n'
+' Don\'t worry if you need to start with just 2 or 3 boxes, you\'ll soon improve.'
+' Try increasing the difficulty as you get better. It\'s a good idea to keep a note of your progress. </p>\n'
+'<p>It\'s best not to try to work out strategies such as repeating the letters silently to yourself, \n'
+'but just to let your mind find its own way of improving, even though this can be frustrating. You\'ll find that \n'
+'success depends as much on avoiding distraction as it does on memorizing.</p>\n'
+'<p>However if you practice (for about 20 minutes a day) you should notice a lot of progress over a period of weeks \n'
+' (which is why you\'ll be pleased you kept a record), and the improvement should carry over to many other activities. \n'
+'You should soon find you feel more alert and bright.</p>\n';
