<h1>Betting game</h1>
<p>Description: This is my first try to create a decentralized application, in the form of a betting game. The game is running on <strong>Ethereum Rinkeby Test Network</strong>.</p>
<p>Popis: Toto je můj první pokus o stvoření decentralizované aplikace, ve formě sázecí hry. Hra běží na <strong>Ethereum Rinkeby Test Network</strong>.</p>
<p>Rules: Players are betting on choosing higher number than randomly generated number from 1 to 100. Possible win is proportionate to the risk player takes- the smaller number player bets on, the more he can win - however, with a smaller chance. </p>
<p>Pravidla: Hráč vsází na zvolení vyššího čísla než náhodně vygenerované číslo od 1 do 100. Možná výhra je přímo úměrná riziku, které hráč podstoupí - na čím menší číslo si vsadí, tím více může vyhrát - ale s menší šancí. </p>
