1. A fluidic die, comprising:
a fluid channel layer defining a number of fluid channels therein, wherein the fluid channels form a number of ribs between the fluid channels;
a slot layer disposed on a side of the fluid channel layer; and
a first fluid slot and a second fluid slot defined in the slot layer that run a length of the fluidic die, wherein:
at least one of the fluid channels is fluidically coupled at a first end to the first fluid slot and is fluidically coupled at a second end to the second fluid slot, and
fluid flows from a first fluid channel to a row of fluid ejection chambers and into a second fluid channel,
wherein the first fluid slot and the second fluid slot have a different alignment relative to rows of fluid ejection actuators in a fluid ejection layer of the fluidic die.
