Why does my recursive function with promises only wait once?

I'm trying to visualize the "Tower of Hanoi"-problem and tried using promises to make the functions wait for one disc's movement to be animated (which I simulated with setTimeout) before continuing to solve the problem. This test-code calculates the correct movements, but only waits for the animation once and then spits out the rest immediately:

    var A = "rod A";
    var B = "rod B";
    var C = "rod C";

    solve(3,A,C,B);

    function solve (n,source,target,spare) {
        var promise = new Promise(function(resolve,reject){
            if (n==1) {
                setTimeout(function(){
                    console.log("move a disc from "+source+" to "+target);
                    resolve();
                },1000);
            }
            else {
                        solve(n-1,source,spare,target)
                .then(  solve( 1 ,source,target      )  )
                .then(  solve(n-1,spare,target,source)  )
                .then(  resolve()                       );
            }
        });
        return promise;
    }

For people not knowing the problem, I simplified the code a bit, essentially the goal is to print "move" seven times with one second of delay between each of them:

    solveTest(3);

    function solveTest (n) {
        var promise = new Promise(function(resolve,reject){
            if (n==1) {
                setTimeout(function(){
                    console.log("move");
                    resolve();
                },1000);
            }
            else {
                        solveTest(n-1)
                .then(  solveTest( 1 )  )
                .then(  solveTest(n-1)  )
                .then(  resolve()       );
            }
        });
        return promise;
    }
