Function OCaml函数类型问题

我正在尝试编写一个Caml函数，但在键入时遇到了一些问题。功能是：

let new_game size count gens =
  let rec continueGame board  = function
     0 -> ()
    |n -> drawBoard board size;
          continueGame (nextGeneration board) (n-1)

 in
 continueGame (seedLife (matrix 0 size) count)  (gens) ;;

以下是其他功能的类型：

val drawBoard : int list list -> int -> unit = <fun>
val seedLife : int list list -> int -> int -> int list list = <fun>
val nextGeneration : int list list -> int list list = <fun>
val matrix : 'a -> int -> 'a list list = <fun>

---

为什么会发生此错误？我如何解决它？

seedLife接受3个参数，但只传递了2个

  continueGame (seedLife (matrix 0 size) count)  (gens);;
             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 Error: This expression has type int -> int list list
        but is here used with type int list list
