L BLOCK

The L Game is a two-player game played on a 4x4 square board. Each player has a 3x2 L-shaped piece, and there are two 1x1 neutral pieces.

Rules
On each turn, players must move their L piece and may optionally move a neutral piece (or both pieces for a much easier game) to an unused spot.
The game is won by leaving the opponent unable to move their L piece without overlapping others.

Single player
Move the blue or red L , then the neutral block buttons to place the pieces. Then press the red [APP PLAYS RED] / [BLUE PLAYS RED] button for the computer's move.

Two-player
Press the blue [1 PL] button to display the red L arrow buttons. The button will display [2 PL]. Then take turns alternately choosing the red or blue buttons. You can always let the L BLOCKS app play for you using the [APP PLAYS BLUE] OR [APP PLAYS RED] BUTTONS.

Overlap warning!
If two or more pieces overlap, the green bar at the top of the screen turns red. If you try to use the [APP PLAYS BLUE/RED] buttons, tyou will be warned to move a piece until there are no overlaps before being permitted to continue.

The L Game was invented by Edward de Bono and introduced in his book "The Five-Day Course in Thinking" (1967). There’s a button linking to L Game’s Wikipedia page at the bottom of the screen.

I would appreciate any constructive suggestions you might have.
