All I need is a simple timer that is displayed and counts up while a game is being played.

Here is a simple example. You should be able to adapt the concepts to your GUI or whatever.
function [] = gui_timer()
% Make a GUI that counts by seconds...
S.fh = figure('name','gui_timer',...
'menubar','none',...
'numbert','off',...
'pos',[100 100 300 150],...
'closereq',@deleter);
S.tx = uicontrol('Style','text',...
'Units','pix',...
'Position',[10 10 280 130],...
'fontsize',60,...
'String','0',...
'backgroundc',get(S.fh,'color'));
S.tmr = timer('Name','TimerCounter',...
'Period',1,... %
'StartDelay',1,... % In seconds.
'TasksToExecute',inf,... % Do until delete
'ExecutionMode','fixedSpacing',...
'TimerFcn',@tmr_tmrfcn,... % Function def. below.
'StopFcn',@deleter); % Function def. below.
guidata(S.fh,S)
movegui('center')
start(S.tmr);
function [] = tmr_tmrfcn(varargin)
% Callback for timerfcn.
S = guidata(findall(0,'name','gui_timer'));
V = str2double(get(S.tx,'string'));
set(S.tx,'string',sprintf('%i',V+1))
function deleter(varargin)
% Callback for stopfcn and figure close.
T = timerfind('name','TimerCounter');
stop(T);
delete(T);
delete(findall(0,'name','gui_timer'))
