Fantasy Bumps is a game of prediction and speculation. Players are in charge of a men's and women's boat and pick athletes entering a bumps race that they think will deliver the best results.
Each boat starts with a budget of 1000 🦀 and these crabs can be spent however you choose. Crews higher up the river will cost more than those lower down, with the headship crew costing 300 🦀 and the footship crew costing 20 🦀. These higher prices come with more risk and more reward, since crews higher up will gain more crabs if they bump or rowover and will lose more crabs if they get bumped.
Athletes gain and lose crabs for their team in two ways:
The value of crews that gain or lose places will change to reflect their new position. Crews that gain places can be sold the next day for more crabs than were spent to buy them, while crews that lose places will return fewer crabs when sold than were spent. The gain/loss is simply the difference in the price of the places.
Athletes that row over or gain places will also be awarded cash payouts, on top of any intrinsic value change. The reward is 7% of their value for a rowover, plus an additional 14% for each place gained. Headship crews are handled slightly differently, and a headship row over is valued at 17.5% to compensate for the fact that they cannot bump.
Rewards and losses are evaluated at the end of each day and there is the opportunity to change your crew lists before the next day's racing. On day one, you will not have enough crabs to pick all high-valued crews so will need to pick your athletes carefully to get value from every seat. Later in the week, if your athletes are doing well, you will be able to pick more and more of the higher-valued crews and take bigger risks for even greater rewards.
While it has no bearing on the mechanics of the game, crews are also assigned a popularity index to help you see which crews other players are backing - This is the average number of seats that players have purchased of that crew. Theoretically capped at 9, a popularity index closer to or above one indicates that the community think this crew will do well, while an index closer to zero suggests your crabs may be better spent elsewhere.
