We consider Distributed Constraint Satisfaction Problems (DisCSP) when control of variables and constraints is distributed among a set of agents. This paper presents a distributed version of the centralized BackJumping algorithm, called the {\\it Dynamic Distributed BackJumping} - \\algoname{DDBJ} algorithm. The advantage is twofold: \\algoname{DDBJ} inherits the strength of synchronous algorithms that enables it to easily combine with a powerful dynamic ordering of variables and values, and still it maintains some level of autonomy for the agents. Experimental results show that \\algoname{DDBJ} outperforms the \\algoname{DiDB} and \\algoname{AFC} algorithms by a factor of {\\it one to two} orders of magnitude on hard instances of randomly generated DisCSPs.
