13 Pieces move as usual, but they all hide a special "power"
14 inspired by Mario Kart:
15 </p>
16 <ul>
17 <li>
18 The pawn (Toad) leaves a "turbo" mushroom on its initial square,
19 or on the intermediate one in case of a two squares move.
20 </li>
21 <li>
22 The knight (Yoshi) let a surprise egg on its initial square.
23 See about egg effect below.
24 </li>
25 <li>
26 The rook (Donkey) put a banana on a square diagonally adjacent to the
27 arrival one, at random, if possible.
28 </li>
29 <li>
30 The bishop (Wario) put a bomb on a square orthogonally adjacent to the
31 arrival one, at random, if possible.
32 </li>
33 <li>
34 The queen (Mario) can play a stealth move once in the game:
35 the opponent will only know that a queen moved - to an empty square.
36 A promoted queen also has this power if not already used.
37 </li>
38 <li>
39 The king (Peach) can "throw a shell" on an enemy reachable by a queen,
40 once in the game. A promoted king also has this power, if not already
41 used. The capture is done remotely without moving.
42 </li>
43 </ul>
44 <p>The king cannot castle, and pawns don't capture en passant.</p>

55 So the goal is to capture Peach :) If pawns promoted into king, then all
56 of them must be captured. Since it still looked too easy, the 4 mentioned
57 objects alter the move played, generally at random:
58 </p>
59 <ul>
60 <li>
61 A king or a pawn arriving on a mushroom advance one square further,
62 while a knight jump another time in the same direction, if possible.
63 Pawns can "eat" objects diagonally too.
64 Mushrooms have no effect on sliders (queen, rook, bishop).
65 </li>
66 <li>
67 A piece arriving on a banana (resp. bomb) is redirected at random by one
68 square in an orthogonal (resp. diagonal) direction. If a piece (of any
69 color!) stands on that square, then it is captured.
70 </li>
71 <li>
72 The effects can cumulate, as illustrated on the diagram: the pawn
73 "captures" the banana on e4, and is then redirected toward e5: mushroom,
74 it jumps to the next square, which sends it on d5 eating the white rook.
75 (We can imagine that the hope was to eat the black knight instead).
76 A piece may ends on its initial square, move back, and so on. That being
77 said, a given object can only be used once on the path.
78 </li>
79 </ul>

92 <p>
93 The egg case is more complex: a move ending on an egg triggers an effect
94 chosen at random, positive or negative. There are four bonus and four
95 penalties. They are introduced in a dual form: first the positive, then
96 the negative.
97 </p>
98 <ul>
99 <li>
100 King Boo (*B) let you exchange the position of any pair of pieces on the
101 board.
102 </li>
103 <li>Koopa (*K) drives the piece back onto its initial square.</li>
104 <li>
105 Toadette (*T) allows to place a new &mdash; random &mdash; piece on the
106 board. If the piece is dropped on an egg, banana or bomb, its effects
107 are applied.
108 </li>
109 <li>
110 Chomp (*C) eats the piece, which is thus captured. If it's Peach, then
111 bad luck, game over :)
112 </li>
113 <li>Daisy (*D) allows to play again with any of your pieces.</li>
114 <li>
115 Bowser (*M) immobilizes the piece (which is surrounded by a light green
116 halo). It won't be allowed to move on the next turn.
117 </li>
118 <li>Luigi (*L) changes the color of a random enemy piece.</li>
119 <li>Waluigi (*W) changes the color of one of your pieces (at random).</li>
