So there are up to 8 camels depending on how many players are participating.
There are 16 different slots at which each of these camels can reside.
At each round, each camel can move 1-3 steps forward, i.e. the dice are 3 sided. Each round of movement is a permutation of dice rolls and is called a "leg". E.g. {red white blue}, {white blue red}, {blue red white}, ... At the very first leg, the camels are placed on slot 1-3 on the board. So they are not really starting off at the first slot.
As the dice are rolled and the camels are placed, if several camels end up on the same location/slot, they are stacked on top of each other. The one on the top, i.e. the one that got the die rolled last is assumed to be first.
On the next round, if a camel of a stack gets its die cast, the camels on top of it will move along and stacks of camels will be stacked on top of other stacks of camels. The camels underneath will not move along. They will stay on the slot.
Between each dice roll, each player can either make bets on which camel will win, or lose, or place a desert/oasis tile into one of the slots on the board. I'm not sure how it is determined which user has this tile in possession, only those who have it can place it. I don't know how the bets are placed, perhaps each player is bound to each camel so the owner of the camel that just moved get to make bets and place the tile. I don't know how many tiles are allowed on the game and how these tiles are distributed between players. I don't know whether bets can be reversed and how those bets are compounded at the end of the race.
The tile as far as I understand can only be placed on unpopulated slots and on slots that come after the slot of the last camel. If a camel lands on a tiled desert slot, it will have to move backwards one slot and ends up at the bottom of the stack on that slot. If a camel lands on a tiled oasis slot, it will move forward one additional slot and end up on the top of that stack. The desert/oasis tile, is a two-sided tile and the player gets to decide which side of that tile to play .
