(t8n: 'fade')[Hello, GCSE A-Levels Chemistry student. There is a bomb inside you that you cannot defuse unless you (link-reveal: 'play my game.')[ (t8n: 'fade')[You are in an infinitely looping chemistry lab, where you can access various labs dedicated to different types of organic chemistry reactions. You will be given an organic synthesis pathway to carry out in a set number of steps. You must follow the synthesis pathway by entering the labs for the correct reactions and collecting the correct reagents in each room. If your final product is wrong or you don't ''complete 5 reactions correctly within 3 minutes'', the bomb will explode. //If your reaction doesn't apply to the current substance, no reaction will happen and you will be returned to the main lab without your number of steps being affected. You may see an undo button on your screen; this is non-functional to prevent cheating, as undoing a turn also resets the timer.// (link: 'Click here if you\'re ready.')[(display:'GEN')] Play [[practice mode->PRACTICE]] where you can choose your synthesis pathway.] ] ]
