  We extend the analysis of the Backgammon model to an ensemble with a fixed
number of balls and a fluctuating number of boxes. In this ensemble the model
exhibits a first order phase transition analogous to the one in higher
dimensional simplicial gravity. The transition relies on a kinematic
condensation and reflects a crisis of the integration measure which is probably
a part of the more general problem with the measure for functional integration
over higher (d>2) dimensional Riemannian structures.
