form a game duration having a predetermined game end time, the game duration comprising a plurality of time-brackets, wherein the game end time is controlled by the server,

initiate an add-on game for a selected set of the electronic user devices participating in the first game, the add-on game relating to the first game, wherein the add-on game comprises a displayable add-on game portion including: (i) a first indicator relating to a time until the game end time, and (ii) a second indicator presenting a current award in case of winning the add-on game,

determine a current probability of winning the add-on game, wherein the probability is dependent on a current time in relation to the predetermined game end time, and the time-brackets each define an increase in the current probability for a successful outcome of the add-on game,

determine upon receiving a bet, for the first game, from a particular electronic user device participating in the first game an outcome of the add-on game for that particular electronic user device based on the current probability for a successful outcome of the add-on game, wherein the current probability for a successful outcome of the add-on game is:

inversely dependent on a difference between the game time and the current time,

increased if the outcome of the add-on game is negative, and/or

dependent on a difference between the predetermined game end time and the current time,

such that the current probability for the successful outcome increases as the current time approaches the predetermined game end time,

select the particular electronic user device as a winner of the add-on game if the gaming outcome is positive,

distribute, to the particular one electronic user device, an award relating to the add-on game,

wherein the award is at least partly dependent on a predetermined ratio of bets provided by the set of electronic user devices participating in the first game,

form a graphical representation of a current status of the add-on game, the graphical representation including the displayable add-on game portion, and
