About Klotz
Klotz is a relaxed block puzzle in the style of 1010!. Each round you
get three polyomino pieces and place them on a square board. Full rows
and columns clear simultaneously. Chain several clears in a row to
build a combo -- and earn specials.
SIX MODES
- Endless -- classic, no time pressure, with a solvability guarantee
- Daily Challenge -- same piece sequence every day, 30-day history
- Levels -- 10 stages with block and ice obstacles, 1-3 stars
- Time Trial -- 180 seconds, combos count double
- Reverse -- clear a pre-filled board before the pool runs out
- Shrink -- the board shrinks inward over time
Plus your own piece sequence from a keyword: replay the exact same
game as often as you like and try to beat yourself.
SPECIALS AS LIFESAVERS
- Bomb -- clears a 3x3 area
- Hammer -- removes a single cell
- Joker -- fills a free cell
Earned through combos and cleared lines. As long as specials are in
your inventory, the game cannot end.
BOARD SIZES
6x6, 8x8, 10x10 or 12x12 -- freely selectable. Difficulty, bonus
frequency and special stock scale with the size.
