Dexterity

This has to be triggered manually by pressing a button, but if there is another flipped tile on the field, all other tiles between the player's position and the other tile will flip, too.

Some grids are filled with stationary blocks, moveable blocks (either pushing them normally or send them flying with a strong kick) and holes.

There are also monsters which need to be avoided.

All five of them have different behaviour patterns and have the ability to reverse already flipped tiles; some of them can even push blocks or destroy tiles.

The monsters can be killed by using blocks against them: pushing them over the borders of the playfield or a hole will kill them.

Alternatively they also can be trapped.

Killed monsters slowly respawn at pre-defined spawn points; this takes place over several phases.

In the "egg" phase, it can be picked up to kill another enemy with it.

Another possible weapon are stunned enemies which stood on a multi-flipped row.

When pushing blocks into a corner, they will disappear and transform into power ups, e.g. bonus points, extra time or a temporary stun of all enemies.

A life is lost when an enemy is touched or the time runs out.

When that happens, all flipped tiles stay flipped.

Dexterity for Game Boy is currently worth €13.75 loose, €67.66 complete in box, and €155.73 factory sealed. Prices are based on real sales and update regularly on Gamevaro.

Dexterity has a steady sales history on the tracked marketplaces, meaning it trades hands regularly and isn't considered particularly rare.

Loose means cartridge or disc only, CIB (complete in box) includes the original box and manual, and sealed means factory-sealed and never opened. For Dexterity, loose is €13.75 and CIB is €67.66 — CIB commands a premium because original boxes and manuals are fragile and often don't survive.

The PAL version of Dexterity is currently worth €13.75 loose, versus €11.29 for NTSC-U. Regional price differences usually come down to print run size and regional collector demand.
