<p><b>Solution</b><br />
&#8211; Open room B, then close it.<br />
&#8211; Open rooms C and E, then close E and C.<br />
&#8211; Open rooms B, D, F, then close D and B.<br />
&#8211; Open rooms C, E, pass through F, and open G.</p>
<p><b>Rules (aka answer to the puzzle)</b></p>
<div style="background-color:black;color:black;">
<p>You start from the topmost room. Reach the bottommost room.</p>
<p>In each room, there are two numbers; the cost (in gems) to enter the room and the number of gems inside the room, in that order. (For example, 4/2 means a cost of 4 gems to enter and you get 2 gems upon entering.)</p>
<p>Gems inside the room don&#8217;t regenerate; once you take them, they won&#8217;t appear again when you come again.</p>
<p>You can close (lock) a room and gain 50% refund. (For example, a room with a cost of 4 gems will refund you 2 gems when you lock it.) You can leave a room without locking it, if you wish.</p>
<p>A room can only be unlocked from the top, and upon locking a room, you must go to a higher room.</p>

<p>So&#8230; I&#8217;m bored. Here&#8217;s the result of my bored mind. I should return to making pencil puzzles&#8230;</p>
