Android error "IF" and "ELSE"

I'm new at Android and I am having a problem with my code.

the software is not showing "Fail" when the user presses the wrong block.

When I debug the code, it is only running the if part, not the else. I want to execute the else condition as well, any suggestions?

private void buttonLogic(View v) {
        List<Integer> tempList = new ArrayList<>();
        for (int i = 0; 1 <= curLevel; i++) {
            if(i!=12)
            tempList.add(buttons.get(i));
           else
                break;
        }
        if (tempList.contains(v.getTag())) {
            curGuess++;
            checkWin();

        } else {
            lostGame();
        }
    }

 private void lostGame () {
        Toast.makeText(this, "Fail!", Toast.LENGTH_SHORT).show();
        disableButtons();
        b_new.setVisibility(View.VISIBLE);

    }
